"The transcendental form of the Lord installed in a temple is not different from the Lord personally. Such a form of the Lord is called arca-vigraha, or arca incarnation, and is expanded by the Lord by His internal potency just to facilitate the devotional service of His innumerable devotees who are in the material world. The material senses cannot perceive the spiritual nature of the Lord, and therefore the Lord accepts the arca-vigraha, which is apparently made of material elements like earth, wood and stone but actually there is no material contamination. The Lord being kaivalya (one alone), there is no matter in Him. He is one without a second, and therefore the Almighty Lord can appear in any form without being contaminated by the material conception. Therefore, festivities in the temple of the Lord, as held generally, are like festivals performed during the manifestive days of the Lord of Dvaraka, about five thousand years ago. The authorized acaryas, who know the science perfectly, install such temples of the Lord under regulative principles just to offer facilities to the common man, but persons who are less intelligent, without being conversant with the science, mistake this great attempt to be idol worship and poke their nose into that to which they have no access. Therefore, the ladies or men who observe festivals in the temples of the Lord just to have a look at the transcendental form are a thousand times more glorious than those who are nonbelievers in the transcendental form of the Lord."
(Srimad-Bhagavatam 1.11.24, Purport)
