“A human being should be inquisitive to know who he is, what the universe is, what God is, and what the relationship is between himself, God and the material world. Such questions cannot be asked by cats and dogs, but they must arise in the heart of a real human being. Knowledge of these four items-namely, oneself, the universe, God, and their internal relationship-is called sambandha-jnana, or the knowledge of one's relationship.” (Shrila Prabhupada, Chaitanya Charitamrita, Adi 7.146 Purport)
