Explanation:

When we hear statements like “God is light” as in the Brahma Sutra (Jyotiradhikaranaat), we are misled into thinking that God enters inert light. The reason is that in a metaphor, we say that God is light. This is only a hidden simile and we should understand that it is just a comparison. It means that God preaches spiritual knowledge and removes ignorance as light removes darkness. The basic concept that God never enters an inert medium helps us in detecting this point. By this basic concept, we can understand whether it is a comparison or the medium of God. God enters only a soul, which is indicated by awareness. It is already clarified that even awareness is only a medium of God and not God directly.
