We have information from the Bhagavad-gita that the Lord appears at particular intervals to adjust a time-worn spiritual culture. Lord Sri Krsna appeared at the end of Dvapara-yuga to regenerate the spiritual culture of human society and also to manifest His transcendental pastimes. Visnu is the authorized Lord who maintains the created cosmos, and He is also the principal Deity who makes adjustments for improper administration in the cosmic creation. Sri Krsna is the primeval Lord, and He appears not to make such administrative adjustments but only to exhibit His transcendental pastimes and thus attract the fallen souls back home, back to Godhead.
