In plain words
But in sva-Dharma, the Ātma's Dharma, there is no room for fear and bewilderment like these. So to follow the Dharma of the Ātma is man's chief duty. So, because all these qualities are in every man, God is also the embodiment of all mankind. Ekovasi sarvabhūtāntarātma. The One alone dwells in all beings as their inner Self. God is not to be seen in some special place, at some special time, or in some special circumstances. Everyone who has good qualities like these is the very form of God. This one the elders called Ṣaṭkāra. Ṣaṭkāra means the one who creates. The one who shines with good qualities. The one who pervades everywhere. The one endowed with every aiśvarya. The one who has come to know all things. The one who, though in everything, has no connection with any of it whatever. Such a one is God. Such a God cannot be recognised by any proof whatever.
Proofs are of three kinds. The proof of perception, the proof of inference, the proof of the word. These are only proofs we have settled on with a worldly eye. God is all-pervading. What proof can they fix for One who is in all beings? That is why they have called God Aprameya. Aprameya means One whom no proof can catch. God has great power of intellect. He is the embodiment of perfect Jñāna. He is Jñāna itself. That is why they have called God, the embodiment of Jñāna, Manu. He has the power and the strength to create the whole world by His will, to sustain it and to make it merge. So they have called God by another name too, Prajāpati. This Paramātma they have also spoken of as the Ātma. Ātma means Brahman itself. Brahman means the consciousness that is in all beings. The Ātma one thing and Brahman another: that can never be. So they have looked upon the divinity that has this consciousness as the Paramātma.
In another place they have spoken of this Brahman-principle as aham. Aham does not mean the Ahaṅkāra that belongs to the body. They have called the blazing light itself aham. Aham means that very form which roots out darkness. Aham has another meaning: the witness. They have called the Paramātma, the witness of all, aham. God is the Lord of what has been born, of what is yet to be born, and of what is. God is the One whose form stays forever unchanged in the three times. They have also called such a God Bhūta-bhavya-bhavat-prabhu. They have also spoken of the form of such a God as Bhāvaḥ. Bhāvaḥ is simply that which is radiant.
