Asamprajnata or Non-distinguished Samadhi YS- I-18

Yoga Sutra I- 18 VIRAMA PRATYAYABHYASA PURVAH SAMSKARASESO'NYAH- By the firmly convinced practice of the complete cessation of the mental modifications, the impressions only remain. This is the other samadhi [asamprajnata or non-distinguished]

A definition from http://en.mimi.hu/yoga/asamprajnata_samadhi.html -Asamprajnata Samadhi supraconscious. The citta and the object of meditation are fused together. The consciousness of the object of meditation is transcended. All mental modifications are checked (niruddha), although latent impressions may continue.

In this commentary of this sutra, Swami Satchidananda continues to talk about samprajnata samadhi (distinguished) with all its four varieties should be practiced. He talks about how the buried seeds can still come up in the conscious mind and pull you back into worldly experience. It is only when all four stages are passed can one progress into asamprajnata samadhi where even the ego feeling is no longer present "and the seeds of past impressions are rendered harmless." He further says in this state, only consciousness is present and nothing else. This is the state of a liberated individual, a jivanmukti, and there is no more getting tossed or involved in worldly matters. It is not meant that the liberated person just goes away from the world or dies, but that it is one who lives and the same time is liberated.

Basically Satchidananda is saying we have to understand nature completely, then bring it under control, push it aside and become liberated. If one just attempts to renounce the world by going to a forest or cave and never being free from the nature that is not liberation. Nature will follow. There is no hiding anywhere. There is no other way than to understand it (Prakriti or Nature), handle it properly and then rising above it.

Samskara - Impression YS I - 50

Samskara(s): Sanskrit word meaning impression left by a previous thought or action; latent tendency; are the seed of our past actions. We all have samskaras in our lives that either help or hinder us. So now we come to the following sutra:

Yoga Sutra I- 50 - TAJJAH SAMSKARO'NYA SAMSKARA PRATIBANDHI - The impression produced by this samadhi wipes out all other impressions.

Swami Satchidananda says in his commentary of this sutra that the impression which comes from the samadhi in which you get ritambhara prajna will block all other impressions. Here everything dies away and there is no more returning back as an ordinary person, who is unaware of his own true nature. When one gets to this stage, the stage of no return, one always retain this knowledge (of his true nature). This stage is when one becomes a realized saint or a jivamukta. The word jivan means one who is lives and mukta means liberated. The jivanmukta lives, eats, talks, does business like everyone else but liberated. This liberated person doesn't get excited. This person as a jivanmukta can do anything, like being involved in the world for the sake of humanity without any personal attachment.

Swami Satchidananda concludes the commentary by stating that a liberated person will not be attached to anything, not have impressions or old thoughts to bring them back to ordinary life. The seeds of desire will be completely burnt up and that liberated person will always live in an unattached state.
