Kṛṣṇadāsa Kavirāja Gosvāmī teaches us first to offer respect to the Pañca-tattva — Śrī Kṛṣṇa Caitanya Mahāprabhu, Nityānanda Prabhu, Advaita Prabhu, Gadādhara Prabhu and Śrīvāsa Prabhu and other devotees. We must strictly follow the principle of offering our respects to the Pañca-tattva, as summarized in the mantra śrī-kṛṣṇa-caitanya prabhu-nityānanda śrī-advaita gadādhara śrīvāsādi-gaura-bhakta-vṛnda. At the beginning of every function in preaching, especially before chanting the Hare Kṛṣṇa mahā-mantra — Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare — we must chant the Pañca-tattva’s names and offer our respects to them.
