"The daily and deliberate exercise to discriminate between what is true and what is false and to give up what is false means meditation. There are many kinds of meditation to begin with, but at the end it all turns into one."
The quote was extracted from the book "I Am That: Talks with Sri Nisargadatta Maharaj" by Nisargadatta Maharaj.
