The living entity labors under the bodily conception of I am this, I am that. My duty is this, and therefore I shall do it These are all mental impressions, and all these activities are temporary; nonetheless, by the grace of the Supreme Personality of Godhead, the living entity gets a chance to execute all his mental concoctions. Thus he gets another body.
