Becoming fully Krsna conscious, one is freed from all dualities and thus is free from the contaminations of the material modes. He can become liberated because he knows his constitutional position in relationship with Krsna; and thus his mind cannot be drawn from Krsna consciousness. Consequently, whatever he does, he does for Krsna, who is the primeval Visnu. Therefore, all his works are technically sacrifices because sacrifice involves satisfying the Supreme Person, Krsna. The resultant reactions to all such work certainly merge into transcendence, and one does not suffer material effects.
