…In this present day, man is very eager to have one scripture, one God, one religion, and one occupation. So let there be one common scripture for the whole world—Bhagavad-gītā. And let there be one God only for the whole world—Śrī Kṛṣṇa. And one mantra only—Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. And let there be one work only—the service of the Supreme Personality of Godhead. (from Introduction to the Bhagavad-gita As It Is)
