CC Madhya 19.114
rūpa-gosāñire śikṣā karā’na śakti sañcāriyā
Due to the great crowds in Prayāga, Śrī Caitanya Mahāprabhu went to a place called Daśāśvamedha-ghāṭa. It was there that the Lord instructed Śrī Rūpa Gosvāmī and empowered him in the philosophy of devotional service.
Parāsya śaktir vividhaiva śrūyate. The Supreme Lord has multipotencies, which the Lord bestows on His fortunate devotees. The Lord has a special potency by which He spreads the Kṛṣṇa consciousness movement. This is explained in the Caitanya-caritāmṛta (Antya 7.11): kali-kālera dharma — kṛṣṇa-nāma-saṅkīrtana/ kṛṣṇa-śakti vinā nahe tāra pravartana. “One cannot spread the holy name of Kṛṣṇa without being specifically empowered by Lord Kṛṣṇa.” A devotee who receives this power from the Lord must be considered very fortunate. The Kṛṣṇa consciousness movement is spreading to enlighten people about their real position, their original relationship with Kṛṣṇa. One requires Kṛṣṇa’s special power in order to be able to do this. People forget their relationship with Kṛṣṇa and work under the spell of māyā life after life, transmigrating from one body to another. This is the process of material existence. The Supreme Lord Śrī Kṛṣṇa personally descends to teach people that their position in the material world is a mistaken one. The Lord again comes as Śrī Caitanya Mahāprabhu to induce people to take to Kṛṣṇa consciousness. The Lord also empowers a special devotee to teach people their constitutional position.
