I’ve also talked about the 3 aspects of consciousness model: seer, seeing, and seen. I illustrate this here.
Another variation on the first is the Adi’s. Adi means beginning with, original, or everything.
1) Adi-Atma: the field of consciousness or Atman, the cosmic Self. This is composed of the 3 aspects of consciousness above. The Atma Kosha.
2) Adi-Deva: the field of creation arising from consciousness, the laws of nature, the devas. Their field is the subtle koshas.
3) Adi-Bhuta: Bhuta is the components, relating to Bhuur and Bhuvar, the gross worlds. Also, the gross koshas. The Mahabhuta are the 5 primary elements.
(Bhuta also refers to that which exists or is manifest, but this is a more materialist view. The sense of existing arises from consciousness aware of itself, aware that it is. )
