There are many śāstric injunctions which give instructions for carving forms of the Lord. These forms are not material. If God is all-pervading, then He is also in the material elements. There is no doubt about it. But the atheists think otherwise. […] There are different procedures and rules and regulations which are followed in temples of Viṣṇu, and devotees go there and see the Deity, the vigraha, and spiritually enjoy the form because all of the Deities are benevolent.
