We can even relate to God as His father or mother. This is the philosophy not only of the Caitanya-caritāmṛta but of Śrīmad-Bhāgavatam as well. There are no other scriptures in the world in which God is treated as the son of a devotee. Usually God is seen as the almighty father who supplies the demands of His sons. The great devotees, however, sometimes treat God as a son in their execution of devotional service. The son demands, and the father and mother supply, and in supplying Kṛṣṇa the devotee becomes like a father or mother. Instead of taking from God, we give to God. It was in this relationship that Kṛṣṇa's mother, Yaśodā, told the Lord, “Here, eat this or You’ll die. Eat nicely.” In this way Kṛṣṇa, although the proprietor of everything, depends on the mercy of His devotee. This is a uniquely high level of friendship, in which the devotee actually believes himself to be the father or mother of Kṛṣṇa.
However, Lord Caitanya's greatest gift was His teaching that Kṛṣṇa can be treated as one's lover. In this relationship the Lord becomes so much attached to His devotee that He expresses His inability to reciprocate. Kṛṣṇa was so obliged to the gopīs, the cowherd girls of Vṛndāvana, that He felt unable to return their love. "I cannot repay your love," He told them. "I have no more assets to give."
