The Sound Incarnation.
Srila Prabhupada: Although there is no Deity, still this Hare Krishna Mantra is considered to be the sound vibration incarnation of Krishna. Actually, we should give more stress in worshiping the incarnation of sound vibration but whenever there is possibility of installing Deities and strictly following the regulations of worship, we shall do this, but the essential part of our activities is to worship the sound incarnation.
