In plain words
There is no form that is not it. There is no substance that is not it. It is present even in the sentient and the insentient. In the world, scientists say that each and every thing is an atom. The whole world is the working of atoms! If there is wood, it is the working of atoms! If there is a mike, it is the working of atoms! It is all a coming together of the power of atoms! So they all called this ‘the atom’. But in spirituality they called this ‘Śakti’. They all said ‘Śakti’. They said ‘energy’. The names differ, but the substance is one! Wherever there is the atom, there divinity is. Every atom has a form. There is no atom without form. The One who dwells in our heart is divinity itself. God has many forms. Divinity is made up of many forms. There is the body; there are legs. There are hands. There are a nose, eyes, ears and a mouth. The body is just all these joined together. If you make each one of these separate, where is body? In the same way, whatever you see in the world, everything is a limb of God! The hills are all of stone, the earth all of clay, the trees all of wood, the body all of flesh. All of them are made of the five elements! All is the working of the five elements. Everything is the form of the five elements. The five elements themselves are the form of the Paramātma. The Paramātma has no separate form.
God must come in human form itself and save man
But Avatāras come down to prove this truth to those who are blind and those who are ignorant. Even those Avatāras do not come in special forms. All the living beings born in the world carry out their own duties themselves. Beasts, birds, worms, insects and the rest, ants and mosquitoes, pass their time without breaking their duties in the least. But the man of today alone forgets his duty. Birds follow season, reason. But for man alone: no reason, no season. That is why God must come in human form itself and save this man who has gone astray.
