When shall I be eager to accept the six Gosvāmīs as my prime guidance? And when will I be able to understand the conjugal love of Kṛṣṇa?" No one should be eager to understand the conjugal love of Kṛṣṇa without undergoing disciplinary training under the six Gosvāmīs of Vṛndāvana.
The saṅkīrtana movement inaugurated by Lord Caitanya is a transcendental pastime of the Lord. "By it I live simultaneously to preach and popularize this movement in the material world." In that saṅkīrtana movement of Lord Caitanya, Nityānanda and Advaita are His expansions, and Gadādhara and Śrīvāsa are His internal and marginal potencies. The living entities are also called marginal potency because they have, potentially, two attitudes—namely the tendency to surrender unto Kṛṣṇa and the tendency to become independent of Him. Due to the propensity for material enjoyment, the living entity becomes contaminated by the material world.
