Translation: 
I have wasted all this time, O unconquerable one, becoming more and more intoxicated by my domain and opulence as an earthly king. Misidentifying the mortal body as the self, becoming attached to children, wives, treasury and land, I suffered endless anxiety.
Purport: 

Having in the previous verse condemned those who misuse the valuable human form of life for mundane purposes, Mucukunda now admits that he himself falls into this category. He intelligently wants to take advantage of the Lord’s association and become a pure devotee once and for all.
