एकं शास्त्रं देवकीपुत्रगीतं एको देवो देवकीपुत्र एव 

मन्त्र अपि एकः तस्य नामानि यानि 

कर्म अपि एकं तस्य देवस्य सेवा 

There is [only] one śāstra, the song of Devaki's son [Kṛṣṇa]

There is only one God, Devaki's son [Kṛṣṇa]

There is only one mantra, also, those that are his names

And there is [only] one karma, service of that God.
