Bhagavad Gita Discovers Quotations

Verily there is no purifier in this world like knowledge. One who becomes purified by Karma-yoga discovers this knowledge within (naturally) in course of time. (See also 4.31, and 5.06).

A person whose mind is unattached to sensual pleasures, who discovers the joy of the Self, and whose mind is in union with Brahman through meditation, enjoys eternal bliss.
