Guru etiquette in temples

[Bhakti Vikasa Swami]

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.
