Caitanya Caritamrta. Adi-lila Chapter 7 First Edition.

I thus explain the truth of the Pañca-tattva. One who hears this explanation increases in knowledge of Śrī Caitanya Mahāprabhu.

The Pañca-tattva is a very important factor in understanding Śrī Caitanya Mahāprabhu. There are sahajiyās who, not knowing the importance of the Pañca-tattva, concoct their own slogans, such as bhaja nitāi gaura, rādhe śyāma, japa hare kṛṣṇa hare rāma or śrī-kṛṣṇa-caitanya prabhu-nityānanda hare kṛṣṇa hare rāma śrī-rādhe govinda. Such chants may be good poetry, but they cannot help us to go forward in devotional service. In such chants there are also many discrepancies, which need not be discussed here. Strictly speaking, when chanting the names of the Pañca-tattva, one should fully offer his obeisances: śrī-kṛṣṇa-caitanya prabhu-nityānanda śrī-advaita gadādhara śrīvāsādi-gaura-bhakta-vṛnda. By such chanting one is blessed with the competency to chant the Hare Kṛṣṇa mahā-mantra without offense. When chanting the Hare Kṛṣṇa mahā-mantra, one should also chant it fully: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. One should not foolishly adopt any of the slogans concocted by imaginative devotees. If one actually wants to derive the effects of chanting, one must strictly follow the great ācāryas. This is confirmed in the Mahābhārata: mahā-jano yena gataḥ sa panthāḥ. “The real path of progress is that which is traversed by great ācāryas and authorities.”

While chanting the Pañca-tattva mahā-mantra, one must chant the names of Śrī Caitanya, Nityānanda, Advaita, Gadādhara and Śrīvāsa with their many devotees. This is the process.

I again and again offer obeisances unto the Pañca-tattva. Thus I think that I will be able to describe something about the pastimes of Lord Caitanya Mahāprabhu.

Praying at the lotus feet of Śrī Rūpa and Śrī Raghunātha, always desiring their mercy, I, Kṛṣṇadāsa, narrate Śrī Caitanya-caritāmṛta, following in their footsteps.

Śrī Caitanya Mahāprabhu wanted to preach the saṅkīrtana movement of love of Kṛṣṇa throughout the entire world, and therefore during His presence He inspired the saṅkīrtana movement. Specifically, He sent Rūpa Gosvāmī and Sanātana Gosvāmī to Vṛndāvana and Nityānanda to Bengal and personally went to South India. In this way He kindly left the task of preaching His cult in the rest of the world to the International Society for Krishna Consciousness. The members of this Society must always remember that if they stick to the regulative principles and preach sincerely according to the instructions of the ācāryas, surely they will have the profound blessings of Lord Caitanya Mahāprabhu, and their preaching work will be successful everywhere throughout the world.
