A quick summary of the Hindu organizational chart, followed by a deeper dive into the wisdom of the Upanishads.

“That which cannot be thought by mind, but by which, they say, mind is able to think: know that alone to be the Brahman, not this which people worship here.  
That which is not seen by the eye, but by which the eye is able to see: know that alone to be the Brahman, not this which people worship here.”
Kena Upanishad
