Brahman Interacts With Himself

From a non-dual perspective there is only one reality. The gods and the Vedas, Upanishin Puras have just Brahman interacting with itself. It's much better to describe it as sentient beings interacting with each other. And people have compared Brahma, Vishnu, Vaishwara, the Father's son and Holy Ghost. But what is the truth of this? There is one underlying being which is shining forth as all of this.
