Sahaja nirvikalpa is nasa, kevala nirvikalpa is laya

Question - How can one function in the world in such a state?
Ramana Maharshi : One who accustoms himself naturally to meditation and enjoys the bliss of meditation will not lose his samadhi state whatever external work he does, whatever thoughts may come to him. That is sahaja nirvikalpa. Sahaja nirvikalpa is nasa [total destruction of the mind] whereas kevala nirvikalpa is laya [temporary abeyance of the mind].

Those who are in the laya samadhi state will have to bring the mind back under control from time to time. If the mind is destroyed, as it is in sahaja samadhi, it will never sprout again. Whatever is done by such people is just incidental, they will never slide down from their high state.

Those that are in the kevala nirvikalpa state are not realized, they are still seekers. Those who are in the sahaja nirvikalpa state are like a light in a windless place, or the ocean without waves; that is, there is no movement in them. They cannot find anything which is different from themselves. For those who do not reach that state, everything appears to be different from themselves.
