Bhagavad-Gītā As It Is is a version of the holy Hindu text, Bhagavad Gita, that contains a translation and commentary by A.C. Bhaktivedanta Swami Prabhupada, founder of the International Society for Krishna Consciousness (ISKCON), commonly known as the Hare Krishna movement. The Bhagavad Gita emphasizes a path of devotion toward the personal God, Krishna. It was first published in 1968 by Macmillan Publishers and is now available in nearly sixty languages and is primarily promoted and distributed by followers of the Hare Krishna movement.
For each verse, the book (in complete editions) includes the Devanagari script, a Latin transliteration, word-for-word Sanskrit-English meanings, and English translation. An extensive commentary by Prabhupada is given throughout, based on various Gaudiya Vaishnava works, including: Ramanuja Bhasya (in Sanskrit); Sarartha-varsini-tika (Sanskrit) by Visvanatha Chakravarti Thakura; Gita-bhusana-tika (Sanskrit) by Baladeva Vidyabhushana; and Bhaktivinode Thakur's Bengali commentaries.
Thus the book advocates the path of bhakti toward Krishna, who is seen as the Supreme Personality of Godhead Himself. It establishes that Krishna is not an incarnation, He is the cause of all causes. He is the source of all incarnations. He is even the cause of Vishnu. It teaches the loving service of the transcendental personality of the Lord.
The Bhagavad Gita As It Is by Prabhupada has been praised by scholars and theologians for providing the Western reader the unique opportunity of seeing how a Krishna devotee interprets his own texts and for giving insights into the original and highly convincing ideas of the Gauḍiya Vaisnava school.
