1. Guru etiquette in temples

    There are many offenses one can commit while serving the Lord, and these are described in the Bhakti-rasamrta-sindhu, Hari-bhakti-vilasa and other books. According to the rules and regulations, no one should accept obeisances in the temple of the Lord before the Deity. Nor is it proper for a devotee to offer obeisances and touch the feet of the spiritual master before the Deity. This is considered an offense. Sri Caitanya Mahaprabhu Himself was personally the Supreme Personality of Godhead, therefore it was not actually offensive to wash His lotus feet in the temple. However, because He was playing the part of an acarya, the Lord considered Himself an ordinary human being. He also wanted to give instructions to ordinary human beings. The point is that even though one plays the part of a spiritual master, he should not accept obeisances or permit a disciple to wash his feet before the Deity. This is a matter of etiquette.
