The Panca-tattva is a very important factor in understanding Sri Caitanya Mahaprabhu. There are sahajiyas who, not knowing the importance of the Panca-tattva, concoct their own slogans, such as bhaja nitai gaura, radhe syama, japa hare krsna hare rama or sri-krsna-caitanya prabhu-nityananda hare krsna hare rama sri-radhe 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 Panca-tattva, one should fully offer his obeisances: sri-krsna-caitanya prabhu-nityananda sri-advaita gadadhara srivasadi-gaura-bhakta-vrnda. By such chanting one is blessed with the competency to chant the Hare Krsna maha-mantra without offense. When chanting the Hare Krsna maha-mantra, one should also chant it fully: Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare Hare Rama, Hare Rama, Rama Rama, 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 acaryas. This is confirmed in the Mahabharata: maha-jano yena gatah sa panthah. "The real path of progress is that which is traversed by great acaryas and authorities."
