CC Ādi 8.13
caitanya-nityānanda bhaja kutarka chāḍiyā
Therefore I say again, lifting my arms: O fellow human beings, please worship Śrī Caitanya and Nityānanda without false arguments!
Because a person who performs kṛṣṇa-bhakti but does not understand Śrī Kṛṣṇa Caitanya and Prabhu Nityānanda will simply waste his time, the author, Kṛṣṇadāsa Kavirāja Gosvāmī, requests everyone to take to the worship of Śrī Caitanya and Nityānanda Prabhu and the Pañca-tattva. He assures everyone that any person who does so will be successful in Kṛṣṇa consciousness.
