In this collection of historic talks on the yoga process set forth by Lord Sri Krsna in the Sixth and Eighth Chapters of the Bhagavad-Gita, Srila Prabhupada deeply probes the nature of consciousness, meditation, karma, death, and reincarnation. Ultimately he describes in detail the process of bhakti-yoga, by which one can easily purify the mind and elevate the consciousness to a state of ultimate peace and happiness.
