In Reality there is only One. In Illusion there are many. The reason why there is so much confusion as to whether there is one God or many is because God is so infinitely One.
Even to say "There is one God" is wrong. God is so infinitely One that He cannot even be called One. One may only say "One Is." The word "God" is only an attempt to give that One a name, for in actuality He has no name. Even to say that God is One implies there is the possibility of two. For one to say there are many Gods is madness.
God is that "One" playing innumerable roles.
For example, E. is sitting with his eyes closed and in his imagination he creates innumerable things, and in the very act of imagining them he preserves them. Then he opens his eyes, and in so doing destroys all the things his imagination has created and held together. Thus the same one E. played different roles, that of creator, sustainer and dissolver.
Again, when H. is sleeping and is in sound sleep—which is the Original State of God—people say H. is asleep; but H. in his sound sleep is not even H. (—is not conscious of himself even as H.). When the same one H. wakes up, people say, "H. is awake"; and when the same one H. brushes his teeth, people say "H. is brushing his teeth." The same one H. is seen and understood to be walking, running about, speaking, singing, etc. The same one H. is merely playing different roles. In reality, H. cannot be more than one, for there is but one H...
All that we can ever say is "God Is" or “One Is."
There are two things that exist: One and Many. One we call God; Many we call Illusion. Why? Because in Reality only One Is. Even to call this One, "One," is not right: One IS.
It is best for all to ask God, Baba: "O Baba! You who cannot but be One, make me one with You."
