Bhagavad-gita As It Is

BG Chapters 1 - 6

BG 4.2, Purport: Since there is a great need of an edition of the Gītā in English, as it is received by the paramparā (disciplic succession) system, an attempt is made herewith to fulfill this great want. Bhagavad-gītā—accepted as it is—is a great boon to humanity; but if it is accepted as a treatise of philosophical speculations, it is simply a waste of time.

BG 6.6, Purport: Unless the mind is controlled, the practice of yoga (for show) is simply a waste of time. One who cannot control his mind lives always with the greatest enemy, and thus his life and its mission are spoiled.
