Śrīla Prabhupāda is the pre-eminent ācārya of the Gauḍīya Vaiṣṇava sampradāya of our time. His voyage on the Jaladuta thirty years ago marked the beginning of a spiritual revival, and the twelve years after his arrival in America saw the Hare Krishna movement spread to major cities worldwide. For millennia, the Vedic tradition had been hidden behind the boundaries of India and within Sanskrit and the vernacular languages. To a world immersed in a materialistic ethos, Śrīla Prabhupāda revealed the wisdom of this timeless philosophy.
