There are lower and higher forms of samadhi. In the lower, the yogi attains identification with the spiritual teacher, guru or deity he has chosen to contemplate. In the highest form there is no separation between Atman and Brahman. As Shankara describes it: “There is no longer any identification of the Atman with its coverings.” This is the great mystery of the inner path of Hinduism.
- Shankara, quoted in Prabhavananda and Isherwood, How to Know God, p. 93.
