Saint Vidura’s inquiry is very relevant. The word artha-vit, which refers to one who knows how to discriminate between reality and unreality, is very significant in this connection. An artha-vit is also called paramahaṁsa. A paramahaṁsa accepts only the active principle of everything. Just as a swan accepts only the milk from a mixture of water and milk, a paramahaṁsa accepts only the Supreme Personality of Godhead as his life and soul, neglecting all external, material things. Dhruva Mahārāja was in this category, and due to his determination he achieved the result he desired, but still, when he returned home he was not very pleased.
