The controlling Deities of the living beings in the mundane worlds are the three purusa-avataras. But the potent energy displayed by Sri Krsna is far more extensive than that of the purusas. Sri Krsna is therefore the original father and Lord who protects all creative manifestations through His various plenary portions. Since He sustains even the shelters of the collective living beings, there is no doubt that Sri Krsna is the original Narayana.
