Hello. I'm new to the forum, and equally new to the techniques described herein. I have a question I want to ask out of pure curiosity, and I hope my ignorance is well-tolerated.

When a statement is made that a certain chakra is a certain color, or that energy techniques effect the etheric body (I understand there are also supposed to be a number of other types of bodies) where does this knowledge originate? Are there people who are able to see it directly, or is it perhaps from old eastern customs? How many of these things do the many practitioners experience themselves, and how many of them are learned from a book?

Thank you for your time and patience, and thank you for helping me understand what's being discussed in these forums.
