Sri Baladeva Prabhu, the original Narayana, is the vaibhava-prakasa of Govinda. He is the original cause of all emanations. The Propagating Prime Cause of individuality or the All-pervading Function-Holder of the Personal Godhead is also Baladeva-He is svayam-prakasa. Sri Baladeva's color is white, different from Krsna. He carries a buffalo horn, which produces more sound than the flute of Krsna. Therefore He is known as the Horn-holder (Singadhrka). Sri Baladeva possesses qualities like Krsna. He is the fountainhead or prime source of the all-embracing, all-pervading and all-extending energy. The actual meaning of these definitions cannot be understood completely using limited mundane terminology.
