…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)
In this present day, people are very much eager to have one scripture, one God, one religion, and one occupation.
Therefore, ekam sastram devaki-putra-gitam: let there be one scripture only, one common scripture for the whole world – Bhagavad-gita.
Eko devo devaki-putra eva: let there be one God for the whole world – Sri Krishna.
Eko mantras tasya namani: and one hymn, one mantra, one prayer — the chanting of His name:
Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare
Hare Rama, Hare Rama, Rama Rama, Hare Hare
Karmapy ekam tasya devasya seva: and let there be one work only — the service of the Supreme Personality of Godhead.
