So this is the wonderful power, inconceivable power, that He is in everywhere, but still, He is aloof, He's aloof from that place. We can feel His energy, but we cannot see because in this material eye we cannot see. But when we develop our spiritual quality—we sanctify our senses—then even within His energy we can see Him. Take for example. Just like electric power is transmitted everywhere. There is wiring. Now, if some electrician is there he can take electric power from anywhere and utilize the electricity. Similarly, His energy is spread all over the universe. When we are transcendentally situated, just like when we become the electrician, then from anywhere we can see God eye to eye. Premāñjana-cchurita-bhakti-vilocanena (Bs. 5.38). That creation, spiritualization of the senses, is possible by devotional service and love. Premāñjana-cchurita-bhakti-vilocanena santaḥ sadaiva hṛdayeṣu vilokayanti (Bs. 5.38). Therefore, as the Lord says, that mayā tatam idaṁ sarvam jagad avyakta-mūrtinā, the Lord is all-pervading all over the universe. Therefore He is within the stone, He is within the earth, He is within the water, He is within the air—everywhere. Therefore, if we make an image of God from anything, either of water, either of stone, either of anything, oh, that is not doll. That is also God. If we have got sufficient devotion, that image also will speak with me, because God is everywhere. Mayā tatam idam sarvam: "I am spread all over, impersonal." But if we make His personal form from anything, either from the stone or from earth or from wood or from anything, or if we create an image of God within myself... There are eight kinds of images recommended in the śāstra, in the Vedic literatures. So any kind of images can be worshiped because God is everywhere.
Now, you can say that why God should be worshiped in images, not in His original form, spiritual form? Yes. That may be a question. But I cannot see spiritual form. That is my difficulty. My senses are so imperfect that I cannot see God immediately in His spiritual form. Therefore, out of His causeless mercy, He appears before you as you can see you, Him. We cannot see just now with our material eyes except stone, earth, wood, something tangible. Therefore He becomes... These forms are called arcāvatāra, incarnation of arcā, conveniently presented by the Supreme Lord so that we can actually see. But the result will be that in the image, if you concentrated your energy, and if you love and offer your, I mean to say, devotion, this will be responded, even from that image.
