The parallel with Kabbalah mentioned above appears to be not very significant and purely coincidental - in as much as anything in esotericism can be "coincidence" - perhaps "archetypal convergence"

The microcosmic orbit diagram from  Mantak and Maneewan Chia Awaken Healing Light of the Tao (Healing Tao Books, 1993), p.170.

Here once again we have pairs of chakras at the front and rear of the body, as well as one at the top and one at the bottom (giving the symbolic four elements and associated cardinal points, as well as any number of associated correspondences one may choose to add). It does not take much imagination to realise there is some connection here, a rather more significant example of archetypal convergence.  Certainly there are differences - Mantak Chia specifically states that these are centers of concentration, not chakras, although they do correspond to specific acupuncture points (which writers like David Tansley and others in turn associate with minor chakras).  There are no etheric vortexes in the Taoist version, little or no psychological associations, and there are more centers.  Moreover, the microcosmic orbit, as it's name indicates, is a a dynamic conception involving the circulation of Ch'i energy.

In the formulation of Barbara Brennan, although front and rear chakras are paired, there is no conception of a circulation of energy in a microcosm orbit that Mantak Chia speaks of, nor is reference made to the Inner line of chakras as represented in tantric yogic iconography.  However, the distinction between Will, Feeling, and Mental Centers is significant, and would seem to correspond pretty much to Mantak Chia's distinction between the rear ascending yang governor channel (= will) and the descending front yin channel (= feeling).  I would suggets here that both are describing the same realities, with the centers often in exactly the same locations, albeit from different points of view.  The circulation of ch'i is a higher movement over the vortex in- and out-take of cosmic energy.  One could even bring in Kabbalah here as the macrocosmic equivalent.  My understanding is what are described here are what I have termed the "Secondary Chakras" - i.e. the energic (whether vortex or circulating) activity of the organs of the etheric bodies.  By studying phenomena like chakras, auras. nadis, etc, we understand more of the nature of the subtle chakras, the sobtle body.
