Hindu Scriptural evidence against making and worshipping idols
(Purport from the Bhagavat Gita - As it Is, translated and commented on
by A.C. Bhaktivedanta Swami Prabhupada)
Hinduism - Idols for concentration but Vedas against Idol worship ?
Bhagavat Gita 7-22 : Endowed with such a faith, he endeavors to worship a particular demigod and obtains his desires. But in actuality these benefits are bestowed by Me alone.
Purport: The demigods cannot award benedictions to their devotees without the permission of the Supreme Lord. The less intelligent living entity does not know this, and therefore he foolishly goes to the demigods for some benefit. But the pure devotee, when in need of something, pray only to the Supreme Lord. A living entity goes to the demigods usually because he is mad to fulfill his lust [for material things]. Devotional service to the Supreme Lord and the worship of a demigod cannot be on the same platform, because worship of a demigod is material and devotional service to the Supreme Lord is completely spiritual.
Bhagavat Gita 7-23 : Men of small intelligence worship the demigods, and their fruits are limited and temporary. Those who worship the demigods go to the planets of the demigods, but My devotees ultimately reach My supreme planet.
Purport: Some commentators on the BG say that one who worships a demigod can reach the Supreme Lord, but here it is clearly stated that the worshipers of demigods go to the different planetary systems where various demigods are situated, just as a worshiper of the sun achieves the sun or a worshiper of the demigod of the moon achieves the moon. It is not that everyone, regardless of whatever demigod is worshipped, will reach the Supreme Personality of Godhead. That is denied here, for it is clearly stated that the worshipers of demigods go to different planets in the material world but the devotee of the Supreme Lord goes directly to the supreme planet of the Personality of Godhead.
Bhagavat Gita 7-24: "The ignorant believe that un-manifest Para Brahma (One God) incarnates or takes manifestations, because they do not completely understand My highest, immutable, incomparable, and transcendental existence."
Bhagavat Gita 7:19-21: "All those who do idol worship, All those who worship demigods are materialistic people."
Yajur Veda 3:32: "...Of that God you cannot make any images."
Yajur Veda 32:3: "God is formless and bodiless"
Yajur Veda 40:8: "All those who worship the uncreated things, they are in
darkness, and you'll enter more into darkness if you worship the created things."
Rig Veda, Vol.8,1:1: "All Praise are to Him alone"
Rig Veda, Vol.6,45:16: "There is only One God, worship Him."
