Samadhi is a term used in Hindu and Buddhist yogic meditation. Samadhi is also the Hindi word for a cenotaph, a structure commemorating the dead (akin to a tomb, but without remains).
Samadhi is a Sanskrit term for the practice which produces complete meditation (among "normal" one). According to Vyasa, "yoga is samadhi" deciphered as complete control (samadhana) over the functions of consciousness (better is it so Higher control, that it Release...).
The exact meaning and usage of the term varies among the Indian religious traditions (such as Hinduism and Buddhism) but its meaning is from 'sam', with (into), together + 'a' towards + 'dha' to bring (to get, to hold). The result is various degrees of veridical coalescent acquisition of truth (samapatti).
Samadhi is the state of being aware of one's Existence without thinking, in a state of undifferentiated - Beingness.
Three intensities (depths) of Samadhi are usually understood
 
1. Laja Samadhi - is latent ("laja"), potential level of samadhi. It begins in deep meditation or Trance - even with movement such as dancing, etc. It is state of joy, deep and general well feeling (Wellness:), peaceful meditative state (also with income from source known as alpha level of brain´s work frequency)
 
2. Savikalpa Samadhi refers to the initial (beginning) state of full valued Samadhi. The mind is still present with work(ing), which is reason for word KALPA (sanKALPA) - which means imagination (sankalpa means wish, which is defined in this example as imagination with will to get it). VIKALPA means "against imagination", because this level of samadhi goes to quiet and open mind by overcoming work of mind - as imaginations are (more than) result of that work). So that level of Sankalpa leeds to the Truth among any binds of mind (which are mostly imaginations). SA means "with" by that way. So SAvikalpa SAMADHI means "Samadhi (upper meditation) with (tendency to) against or better AMONG imaginations.
 
3. Nirvikalpa Samadhi (Sahaja Samadhi)
 
... Upon entering Nirvikalpa Samadhi the differences we saw before have faded and only one and the same Substance is seen with which we then gladly identify. In this condition nothing but pure Awareness remains and nothing is missing to take away from Wholeness and Perfection.
Samadhi is the only stable unchanging Reality. All else is ever changing and does not bring everlasting peace or happiness. Staying in Nirvikalpa Samadhi is effortless but even from this condition one must eventually return to ego-consciousness.
 
Otherwise, this highest level of Samadhi leads to NIRVANA, what means total Unity with logical end of individual form (end of personal soul and also death or dematerialization of the body). However, it is entirely possible to stay in Nirvikalpa Samadhi and yet be fully functional in this world. This condition is known as Sahaja Nirvikalpa Samadhi (sahaja means "spontaneous"). Only the true Enlightened (spiritual Masters and so on) can be Spontaneously Free.
 
Nirvikalpa Samadhi is achieved through the advanced and prolonged practice of Kriya Yoga or other forms of Yoga (or even nonYoga spiritual teaching) and is the state of oneness with the Atman - the true Soul (as entirely consciousness part of the God).In Nirvikalpa Samadhi, all attachment to the material world and all karma is dissolved.
All awareness is withdrawn step by step from the physical, astral and causal bodies until self-realization or oneness with the soul is achieved. During this process, breathing ceases, the heart stops beating. Aware and fully conscious oneness with soul is then achieved in a most loving way and all cells of physical body are flooded with the Ocean of Divine Love and Divine Bliss for any period of duration - hours, days, weeks until the individual shifts his awareness from the soul back to the physical body.
 
For being full functional in this word, he awareness stay in Connection with the Divine, but stay (back) in the body, which is than normally functional. But some "strange" conditions will be there - better health (near invulnerable), better feelings (even for other person who touches the body with soul atached to the Divine) and "miracles" only by presence, speech (wishes!) and gestures (doings) of the Divine person (also called the Enlighted).
 
Nirvikalpa Samadhi is a preparatory step to Maha Samadhi and serves as extreme uplifting of all body vibration (see above) and leads to complete healing of karmic wounds to the open doors to God and divine love for further progress on your way to God.
'Samadhi' is the main subject of the first part of Yoga Sutras called Samadhi-pada.
 
Maha Samadhi (literally great samadhi) is the Hindi word for a realized yogi's conscious departure from the physical body at death. Which is also known as Nirvana.
Maha Samadhi is the final conscious abandoning of the physical body. Every infinitesimal piece of attachment or karma is completely surrendered unto God and dissolved into the Divine Ocean of Love. The individual transcends to worlds beyond karma and returns to God to merge into God or Nirvana which literally menas "extinction" and/or "extinguishing" and is the culmination of the yogi's pursuit of liberation.

Samadhi is a spiritual experience that opens us to the highest state of consciousness and inner bliss. It is stepping into your enlightened nature that is free from all suffering. Samadhi is found through diving into a consistent state of pure consciousness, that is void of attachment to any thought. Samadhi is a deep personal, intimate merging with the divine inside you and all around you. It is being unified with the Universe through your consciousness.

 

When one reaches Samadhi there is a deep knowing that all is one, and that “oneness” is at the core of who you are. Samadhi gives you a moment to moment spiritual experience that is opening, trusting and softening into each new moment of your life. Samadhi is the eternally expanding realization that your ego is not real, and that you (the soul, spirit and divine essence) are what is truly real and will never die.

 

 

Laja Samadhi 

 

It begins in deep meditation or Trance – even with movement such as dancing, etc.

 

It is state of joy, deep and general well-being, and peaceful meditation.

 

 

 

Savikalpa Samadhi

 

‘Savikalpa Samadhi’ refers to the initial (beginning) state of full valued Samadhi. In Savikalpa samadhi, for a short period of time you lose all human consciousness. In this state, the conception of time and space is altogether different.

 

With the human time you cannot judge; with the human way of looking at space you cannot judge. In that samadhi , for an hour or two hours you are completely in another world. You see there that almost everything is done.

 

Here in this world, there are many desires still unfulfilled in yourself and in others. Millions of desires are not fulfilled, and millions of things remain to be done. But when you are in Savikalpa Samadhi , you see that practically everything is done; you have nothing to do.

 

You are only an instrument. If you are used, well and good; otherwise, things are all done. But from Savikalpa Samadhi everybody has to return to ordinary consciousness.

 

Even in Savikalpa Samadhi there are grades. Just as there are brilliant students and poor students in the same class in school, so also in Savikalpa Samadhi, some aspirants reach the highest grade, while less aspiring seekers reach a lower or a middle rung of the ladder, where everything is not so clear and vivid as on the highest level.

 

In Savikalpa Samadhi, there are thoughts and ideas coming from various angles, but they do not affect you. While you are meditating, you remain unperturbed, and your inner being functions in a dynamic and confident manner.

 

 

 

Nirvikalpa Samadhi 

 

Nirvikalpa Samadhi‘ is the highest samadhi that most spiritual Masters attain, and then only if they have achieved realisation.

 

When you have become one with the soul in Nirvikalpa Samadhi , there will be no ideas or thoughts at all. Here nature’s dance stops. There is no nature, only infinite Peace and Bliss. The Knower and the Known have become one. Everything is tranquil. Here you enjoy a supremely divine, all-pervading, self-amorous ecstasy. You become the object of enjoyment, you become the enjoyer and you become the enjoyment itself.

 

It lasts for a few hours or a few days, and then one has to come down. When one comes down, what happens? Very often one forgets his own name. One forgets his own age. He cannot speak properly. But through continued practice, gradually one becomes able to come down from nirvikalpa samadhi and immediately function in a normal way.

 

Generally, when one enters into Nirvikalpa Samadhi , one does not want to come back into the world again. If one stays there for eighteen or twenty-one days, there is every possibility that he will leave the body. But there is a divine dispensation.

 

 

 

Sahaja Samadhi

 

For Sahaja Samadhi, the Supreme’s infinite Grace is required. Sahaja Samadhi comes only when one has established inseparable oneness with the Supreme, or when one wants to show, on rare occasions, that he is the Supreme.

 

Sahaja Samadhi is by far the highest type of Samadhi . In this Samadhi, one is in the highest consciousness, but at the same time he is working in the gross physical world. One maintains the experience of Nirvikalpa Samadhi while simultaneously entering into earthly activities. One has become the soul and at the same time is utilising the body as a perfect instrument.

 

In Sahaja Samadhi, one walks like an ordinary human being. One eats. One does the usual things that an ordinary human being does. But in the inmost recesses of his heart, he is surcharged with divine illumination. When one has this Sahaja Samadhi, one becomes the Lord and Master of Reality. One can go at his sweet will to the Highest and then come down to the earth consciousness to manifest.

 

 

Mahasamadhi

 

Mahasamadhi is the final conscious abandoning of physical body. To achieve Mahasamadhi all karma needs to be completely dissolved – requiring that that individual has at least achieved self realization or soul realization (Samadhi) before being able to realize Mahasamadhi.

 

The physical body dies. Spirit doesnt exist anymore then, that´s why it is called liberation/freedom… Then the spirit is including in everything & everywhere for ever – that´s is Oneness (or unity or infinity or universal consciousness or God) = that´s all is the same, only used different names for it. Every person that reached Samadhi /state without ego/ is beyond karma. Every this kind of living person is free & is going to “die” into mahasamadhi where become God at all, no more births as a human being.  Become ONE with everything forever.

Nirvikalpa samadhi cannot be explained by any individual, no matter how great he is. It is an experience which can be understood only by trying to identify and become one with someone who has attained the experience. We must try to enter into the experience rather than ask the experience to come to our level. When we enter into nirvikalpa samadhi, the experience itself is the reality. But when we want to tell others, to put it into words, we have to come down very far and use the mind; we have to couch the experience in human concepts. Therefore, the consciousness of nirvikalpa samadhi can never be adequately explained or expressed. The revelation of the experience can never be like the original experience.

 

I am trying my best to tell you about this from a very high consciousness, but still my mind is subtly expressing it. In nirvikalpa samadhi we have no mind. We see the Creator, the Creation and the Observer as one Person. There the object of adoration and the person who is adoring become totally one; the Lover and the Beloved become totally one. We go beyond everything, and at the same time we see that everything is real. Here in the ordinary world I will say you are unreal and you will say I am unreal because of our different views. But in nirvikalpa samadhi we go beyond all differences: there the mind does not function at all.

 

When we enter into nirvikalpa samadhi, the first thing we feel is that our heart is larger than the universe itself. Now we see the world around us, and the universe seems infinitely larger than we are. But this is because the world and the universe are now perceived by the limited mind. When we are in nirvikalpa samadhi, we see the universe like a tiny dot inside our vast heart.

 

In nirvikalpa samadhi there is infinite Bliss. There is nothing in comparison to the quantity, not to speak of the quality, of that Bliss. Bliss is a vague word to most of us. We hear that there is something called Bliss, and some people say they have experienced it, but most of us have no firsthand knowledge of it. When we enter into nirvikalpa samadhi, however, we not only feel Bliss, but we grow into that Bliss.

 

The third thing we feel in nirvikalpa samadhi is Power. All the power that all the occultists have put together is nothing compared with the Power we have in nirvikalpa samadhi. But the power that we can take from samadhi to utilise on earth is infinitesimal compared with the entirety. It is like what we require to blink our eye. All this I am expressing through the mind; it is not exact. But I cannot express with words more of the truth that I have realised.

 

I wish to say only that to enter into any level of samadhi is infinitely easier than to transform the human consciousness into the divine consciousness. That I have been trying to do, you have been trying to do, the Supreme has been trying to do. All of us here are trying for only one thing, and that is the transformation of human nature—physical, vital, mental and psychic. When that is done, perfect Perfection will dawn both here on earth and there in Heaven.

 

How can this transformation take place? Through aspiration. The world has to aspire, creation has to aspire, and only then can the spiritual Masters bring down Heaven onto earth. Heaven, as we say, is a state of consciousness. In samadhi, all is Heaven, all is Bliss, Light, Peace. But when we come down into the world again, all is suffering, darkness, fear, worry. How can we make a conscious connection between this world of ours and the highest state of samadhi? Through constant aspiration. There is no other medicine but constant aspiration, not for a day or two, but for a whole lifetime. To realise God takes many, many incarnations. But when you have a fully realised spiritual Master, it becomes much easier. It may take you one incarnation, or two, or three or four. Otherwise, for a normal human being it takes many, many hundreds of incarnations, even to attain the higher experiences or so-called minor realisations. But a realised Master knows the souls and stays in the souls. Since he can do this, it is easy for him to deal with each aspirant according to his soul’s necessity, for his soul’s development and fulfilment.

Kevalya Nirvikalpa Samadhi:

 

With this union with Universe consciousness, the soul now knows itself not through the mind, but through itself. The soul is now beyond mind. He experiences Being Universe consciousness all the time through his intuition. This self-knowledge of the soul is Self-realisation, which does not come and go. It is permanent. He is enlightened forever. He has at last broken the veil of ignorance—Maya is finally defeated. There are now no limits! This state of God-consciousness /Universe consciousness is infinite and characterised by understanding, love and happiness. He has entered Eternity!

 

Now there are no more thoughts or ideas. There is only peace and bliss. The knower and the known (soul or atman) have become one. This divine bliss is all pervading. This is the highest samadhi and can be achieved only after self- realisation (identified with the soul). The yogin has merged with Reality or his soul and is completely unaware of the external world. The mind is immersed into the light of the Self. It is compared to a flame that burns quiet and steady, unaffected by the external breeze. With or without the help of a perfect master, the sadhak has entered spontaneously into Nirvikalpa, after experiencing Nirvana. He can achieve that only after he has relinquished his sanskaric ties and worldly interests. He has already given up all his worldly fetters. There are now no obstacles to overcome or objects to achieve and therefore no effort is needed. The transition is very spontaneous. His individual mind has been annihilated and his consciousness has now merged with the Absolute. He has attained final emancipation through breaking the veils of Maya. He is now a Siddha (God-realised being/Universe consciousness) himself. However, once he comes out of this Nirvikalpa State, the movement of the body, his perceptions including sight and sound, and the arising of the mind will bring him back to the phenomenal world. This Nirvikalpa Samadhi State is said to have a limit of 21 days, but actually there is no time limit. After returning to normal consciousness he has to relearn the ways of the world again. At first, the Siddha forgets his name and age, after returning to normal consciousness. He really does not want to come back to the world at all. But some are given the grace to come back—primarily to teach or to lead.

 

When the kundalini reaches the seventh or crown chakra, we experience the third member of the Trinity – God the Father or Brahman – often as a light transcending creation. This experience is known as Kevalya Nirvikalpa Samadhi or Brahmajnana, God Realization, samadhi without form. It  brings with it a temporary heart opening after which the heart closes again. Kevalya Nirvikalpa Samadhi, which is temporary, while the Samadhi lasts. In Kevalya the heart (the hridayam or spiritual heart, rather than the heart chakra) opens temporarily but in Sahaja (see bellow) the heart opens permanently. The Heart is the seat of Jnanam -wisdom- as well as of the granthi -knot of ignorance-. It is represented in the physical body by a hole smaller than the smallest pin-point, which is always shut. When the mind drops down in Kevalya Nirvikalpa Samadhi, it opens but shuts again after it. The hole called the Heart as a small as a pinpoint is always shut, being the knot of ignorance which ties the body to consciousness.

 

When the mind drops in the temporary Kevala Nirvikalpa it opens but shuts again. In Sahaja it remains always open. In Kevala Nirvikalpa Samadhi one is not free from vasanas and does not, therefore, attain Mukti. Only after the samskaras have been destroyed can one attain salvation. Even though one practices Kevala Nirvikalpa Samadhi for years together, if one has not rooted out the vasanas, he will not attain salvation. Kevalya can be compared to a glimpse of the Self, whereas Sahaja is a permanent and natural state of Self-Realization.

 

By repeated practice one can become accustomed to turning inwards and finding the Self. One must always and constantly make an effort, until one has permanently realized. Once the effort ceases, the state becomes natural and the Supreme takes possession of the person with an unbroken current. Until it has become permanently natural and your habitual state, know that you have not realized the Self, only glimpsed it. When the Self is glimpsed in Kevalya, it is a prelude to Self-Realization, when it becomes permanent Sahaja, it is Self-Realization, Liberation.

Sahaja Nirvikalpa Samadhi:

 

It is divinity in action and is experienced only by the Sadguru. It is preceded by Nirvana and Nirvikalpa Samadhi. This state is beyond mind as consciousness is entirely withdrawn from physical forms, subtle forms and the formless realms. There is no thought except the ‘I am’ consciousness. He is already in the Ultimate State of Consciousness all the time. And yet the yogin is still working in the gross physical world at the same time. He uses the body, emotions and mind as instruments, but there is no identification with them. Throughout his waking hours he is a Siddha in Nirvikalpa Samadhi.  He has transcended the three instruments and is totally absorbed in Universe consciousness. He is in Nirvana and the experience of the world leaves him uninvolved. He is now God-conscious/Universe consciousness and has no individuality. When in this state of Nirvana he is experiencing unlimited individuality. The yogin has already realised his soul and is with Reality throughout the remainder of his life. He is able to use his body-mind organism in the worldly activities. Externally, he is like any ordinary man, but internally, he is with the Absolute. The thinking mind is dead and he is immersed into the Self throughout. It is now only impersonal Consciousness that is acting out the remaining portion of his life. It is like a river discharging into the ocean and its identity is lost. He remains in this state of bliss and happiness without effort. He only uses the working (not the thinking) mind. Out of the not too many Siddhas, very, very few of them may descend down from the 7th plane of consciousness after achieving Sahaja Samadhi. These very few Sadgurus become Avatars. Here they live a life of Universe consciousness and experience God/Universe consciousness everywhere. The small and menial jobs that they perform are never too little for them.

 

The Sahaja Nirvikalpa Samadhi is permanent and in it lies liberation from rebirths.

In Kevalya, the heart (the hridayam or spiritual heart, rather than the heart chakra) opens temporarily but in Sahaja the heart opens permanently.
