Pañca-tattva mantra

CC Ad 7.4

• One should know that Śrī Caitanya Mahāprabhu is always accompanied by these other tattvas. Therefore our obeisances to Śrī Caitanya Mahāprabhu are complete when we say śrī-kṛṣṇa-caitanya prabhu-nityānanda śrī-advaita gadādhara śrīvāsādi-gaura-bhakta-vṛnda. 
• As preachers of the Kṛṣṇa consciousness movement, we first offer our obeisances to Śrī Caitanya Mahāprabhu by chanting this Pañca-tattva mantra; then we say Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare.
• There are ten offenses in the chanting of the Hare Kṛṣṇa mahā-mantra, but these are not considered in the chanting of the Pañca-tattva mantra, namely, śrī-kṛṣṇa-caitanya prabhu-nityānanda śrī-advaita gadādhara śrīvāsādi-gaura-bhakta-vṛnda. Śrī Caitanya Mahāprabhu is known as mahā-vadānyāvatāra, the most magnanimous incarnation, for He does not consider the offenses of the fallen souls.
• Thus to derive the full benefit of the chanting of the mahā-mantra (Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare), we must first take shelter of Śrī Caitanya Mahāprabhu, learn the Pañca-tattva mahā-mantra, and then chant the Hare Kṛṣṇa mahā-mantra. That will be very effective.
