“Love of Godhead is the ultimate benediction for all human beings.” Śrī Caitanya Mahāprabhu is the bestower of this great benediction.
“In the Age of Kali, people who are endowed with sufficient intelligence will worship the Lord, who is accompanied by His associates, by performance of saṅkīrtana-yajña.” (Bhāg. 11.5.32)
…Śrī Caitanya Mahāprabhu is always accompanied by His plenary expansion Śrī Nityānanda Prabhu, His incarnation Śrī Advaita Prabhu, His internal potency Śrī Gadādhara Prabhu and His marginal potency Śrīvāsa Prabhu. He is in the midst of them as the Supreme Personality of Godhead. 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. (Purport from Sri Caitanya-caritamrta, Adi-lila 7.4)
