As long as we are conditioned and we have not established our eternal connection with the Lord, we are incomplete. And because we are incomplete we are always looking for something to compensate for that incompleteness. Only those who are self-satisfied are complete, and how can one be self-satisfied, unless he understands who he really is? Jivera svarupa haya — kṛṣṇera nitya-dasa -- One is the eternal servant of Krishna, but if one doesn’t understand, or doesn’t act in that capacity, then one cannot feel satisfied.
