This is the list of 108 of the most important slokas from the Bhagavad-gita As It Is (1972 Macmillan Edition) by His Divine Grace A.C. Bhaktivedanta Swami Prabhupada. The index to these verses was taken from the Bhakti-sastri Study Guide compiled by Atmatattva dasa as used by the Bhaktivedanta Academy in Mayapur. [*Note for this collection of slokas, we are using the Original Translations rather than the later re-vised Translations. These were the Translations that Srila Prabhupada approved and which were memorized by heart, by all of the early disciples of His Divine Grace.]
These are important verses for memorizing. Srila Prabhupada has said, that when you quote a verse, your argument becomes authoritative.
