“ ‘When the flame of one candle is expanded to another candle and placed in a different position, it burns separately, and its illumination is as powerful as the original candle’s. Similarly, the Supreme Personality of Godhead, Govinda, expands Himself in different forms as Viṣṇu, who is equally luminous, powerful and opulent. Let me worship that Supreme Personality of Godhead, Govinda.’
This is a quotation from the Brahma-saṁhitā (5.46).
