I have heard that all consciousness arise in hadaya vatthu rupa (blood inside the heart) except the five doors perceiving consciousness (Cakku vinnana, Sota vinnana, Ghana vinnana, Jeevha vinnana, Kaya vinnana).
There are some research articles on the internet about the impact on the heart due to brain damage. So one can argue that the brain is merely an organ which supports the functionality of other organs and hadaya vatthu rupa is the place where consciousness originate. Another one can argue the other way around.
So my questions are:
- Where does the consciousness (cittas) originate inside the body? Is it in the brain or hadaya vatthu rupa?
- Consciousness is nāma (not material/formless). Then how can we talk about a place of origination of it?
