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 Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, 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.
