Hi,Caraka wrote: It is the appearance of Mara that is not so clear. Is this a physical appearance you think, ie. can be touch, seen, talked to like anything else that is worldly, or is this an appearance we cannot see with our physical five senses?
Your question relates to the invisible world, devas.
One of the monk I knew claimed that he attained jhanas and has the knowledge of that world explained that it is the realm of consciousness which why modern science can't easily measure it. By consciousness, most people will think it is subjective, but I think about something as objective consciousness. I don't know much but I think revolution new views/ methods are needed to understand this realm in modern language.
Also, modern understanding of consciousness is indirectly through physical world, i.e measure physical state of the brain. Consciousness is a key problem in human history, it is so obvious to human but is very hard/ impossible to measure directly in physical world that why most scientists easily accept consciousness is something physical, i.e the current in brain, but in reality, it is not.
