O my friend, please, therefore, chant the glories of the Lord, who is meant to be glorified in the places of pilgrimage. He is unborn, and yet He appears by His causeless mercy upon the surrendered rulers of all parts of the universe. Only for their interest did He appear in the family of His unalloyed devotees the Yadus.
