The real interest of the living entity is to get out of the nescience that causes him to endure repeated birth and death. The only remedy is to surrender unto the Supreme Personality of Godhead through His representative. Unless one renders devotional service unto the Supreme Personality of Godhead, Vasudeva, one cannot possibly become completely detached from this material world, nor can he possibly manifest real knowledge.
