"That the Lord is represented in everyone's heart is a fact, and therefore the highly advanced devotee offers his respects to every living entity, considering that the body is the temple of the Lord. But it is not possible for all men to come to that stage of life immediately, because that stage is for the first-class devotee. The second-class devotee can consider the Vaisnavas, or the devotees of the Lord, to be representatives of Krsna, and the devotee who is just beginning, the neophyte or third-class devotee, can bow his head before the Deity in the temple and before the spiritual master, who is the direct manifestation of the Supreme Personality of Godhead. In the neophyte stage, in the intermediate stage, or in the fully advanced perfected stage, one can make the function of the head perfect by bowing down before the Lord or His representative. Similarly, he can perfect the function of the eyes by seeing the Lord and His representative. In this way, everyone can elevate the functions of the different parts of his body to the highest perfectional stage simply by engaging them in the service of the Lord or His representative. If one is able to do nothing more, he can simply bow down before the Lord and His representative and drink the caranamrta, the water which has washed the lotus feet of the Lord or His devotee."
(Krishna Book, Chapter 80)
