A state of intense concentration and perfect tranquility achieved through meditation. In Hindu yoga this is regarded as the final stage, at which union with the divine is reached.
Elucidation of Samadhi by Sri Ramana Maharshi:
| Sleep | Savikalpa Samadhi | Kevala Nirvikalpa Samadhi | Sahaja Nirvikalpa Samadhi |
| (1) Mind Alive | (1) Mind Alive | (1) Mind Alive | (1) Mind Dead |
| (2) Sunk in Oblivion | (2) Holding on to Reality with effort | (2) Merged and Sunk in Light | (2) Resolved into the Self |
| (3) like a bucket with the rope left lying in the water in a well | (3) Like a river discharged into the ocean and its identity lost | ||
| (4) to be drawn out by the other end of the rope | (4) A river cannot be redirected from the ocean |
