A question was asked: what is the relationship between the chakras and the different bodies (mental and emotional) of man?
The first seven bodies of man gather information (process light) from the environment in different ways and in different forms. The seven different types of information accessed by the bodies, are then downloaded through the seven chakras into the endocrine system where the seven different endocrine glands provide it as noncognitive information to the minds of man.† (But isn’t this in one of the books?)
By the way, I held an entire retreat on this pathway of light. Granted, it was some years ago, because I was still living in the big house. The theme was that every part of the endocrine system is an intuitive 'third eye', but that the communication pathways have been interrupted...
†There are more chakras than just seven. But there are also more light bodies than seven.
