Why not then focus your interest on 'kundalini'. Seems to me its the same force - different name. There appear to be many roads to the same destination & the yogic methods are much more available. I would think you would stumble across some of the information you are looking for there as it does seem there is a common 'root' teaching the rest evolved from in different regions incorporating the beliefs of the region into the art/path.
I suppose Im saying approaching from another direction may reveal some more of the info you are looking for.
