A question for the advanced

[Sacred Fool]

However, neglecting the lower when striving towards upper balance would be folly, and should be considered to be spiritual bypassing; a potentially dangerous state of lower-upper imbalance...

Just to tack on a thought here, a wanderer from an higher density would already be advanced in the higher energy centers and would not be coming here for that kind of work.  If the lower area seeks and the higher area is that which is sought, then the opportunity here is to further tune the seeking in the lower energy centers.
From this perspective, one might do well to seek diligently to find in these lower centers the vibrations which most closely correspond to what one most deeply is.  I.e., in 3D one has greater opportunity to purify the desire to seek and to serve.  The experience in the higher centers, in some sense, is all built upon the intensity of the lower yearning, as the higher answers the call of the lower.  In the same sense--speaking in symbolic terms--the feminine responds to the seeking of the masculine.
