Revised edition of C W Leadbeater The Chakras, ( annotations by Kurt Leland) suggests the western system of chakras relates to the mortal personality, linked to the etheric double, and the astral and mental body. ( physical health, emotional happiness and intellectual and psychic power) Also that the eastern system concerns the immortal individuality , often linked to the casual body. This is suggesting the reason why chakra systems may be perceived differently .
Suggestion being made is that there could be 7 chakras for each of our 7 bodies( vehicles of consciousness) . Each wheel/ chakra/ revolving disc, are points of connection where energy flows from one body to the next body. So I suppose each chakra is connected to its similar chakra to its higher body. 49 Chakras !
I suppose there's only so much we can do in physical.
