What is that bhakti? We know navadhā-bhakti and all bhakti-rasa as told and explained in Śrīmad-Bhāgavatam, and I gave examples. Bhakti-rasa-sāra is gopi-prema, moreover, rādhā-prema to Kṛṣṇa; and that prema—Kṛṣṇa wanted to taste. That is why Śrī Kṛṣṇa appeared as Śrī Caitanya Mahāprabhu. So, this is the sum and substance, the essence of all bhakti-rasa.
