"So this arca-vigraha which you are worshiping, it is recommended by sadhu, by acarya, by sastra. It is not poetic imagination. Don't think that Krishna's form has been carved by the sculptor by some poetic imagination. No. Sadhu sastra guru vakya. It is confirmed by the sadhu, by sastra, by acarya. So why? To give us facility. Give us facility."
(Srila Prabhupada lecture, Nairobi, October 30, 1975)
