In plain words
God is the body, pure as the sky; God is the eye: the stars, the sun, the moon; God is the … of the pervading wind; God is the … of the ocean.
Students!
God is purer than the sky. Sun, moon, stars and all the rest are also the eyes of God. God is He who pervades everywhere, like the air. If we are to recognise such Divinity, it is only when we have well recognised the principle of the body, the senses, the Manas and the Buddhi, man's instruments, that this vast, this pure, this holy Ātma-principle becomes clear to us.
Know Me also as the Kṣetrajña in all the Kṣetras, O Bhārata; the knowledge of Kṣetra and Kṣetrajña: that is Jñāna, in My view.
The whole world is the blended form of Kṣetra and Kṣetrajña. Man's body is the very reflection of Prakṛti. Whatever things sentient and insentient there are in the universe, all of them are contained in man's body itself. This whole world is only the reflections that are in man. Reflection of inner being. But it is not enough merely to recognise this body, Manas, senses and Buddhi. The Kṣetrajña who recognises this Kṣetra exists apart. Only when we recognise the Kṣetrajña do we have no need to worry over the Kṣetra. Until then, though, we must make the proper effort to experience the Kṣetra in the proper way. To know this Kṣetrajña, we need Jñāna. What is this Jñāna? Is it merely bookish Knowledge? It is not. Superficial Knowledge? It is not. General Knowledge? Not at all. Discrimination Knowledge? This is individual. Practical Knowledge: this too is individual. It is held within limits. All these are only physical, worldly kinds of knowledge.
