I would say, bhakta, that those categories are fine for the root level of our being. We should, after all, be looking for about four basic `spokes.' So, the fight vs. flight (often associated with this center of awareness), the urge to sustain ourselves and reproduce - all these, as we know, are four very
basic urges. Now move up.
Six `spokes' - and in the sacral center we will need to consider more extensions of our awareness with relation to the world around us ... and a greater self-awareness and self-understanding (model, conception of being) that result.
So on as we consider more complicated emotional states (not quite thought, but definitely urges which transcend the purely sexual) in the solar plexus ... and 10 `spokes' -
- then 12, true thoughtforms, and something quite worthy of the lateral extension toward and in-between our neighbors (represented by the outstretched arms) ...
... and the Divine Unit stirs, becomes Active, while 16 petals vibrate in evocation of the 96 (containing the pairs of opposites and the future seed of all harmonizing & equilibrating therein).
Interesting, here, that the initial 4 basic modes of conscious activity are trebled in the number of spokes of the 4th center (the heart), then quadrupled in the throat, while the brow center can be considered a factor of the sacral center (6 spokes, lower creativity) times the throat (16 spokes, higher creativity) - resulting in the 96-petalled lotus of the integrated personality ... guiding, directing and subjugating the lower self.
What does this leave? In the exoteric and simplest study, the 96 of lower, form-based experience
raised by the power of ten, the perfect number (itself etched into our anatomy via the 10-spoked
Manipura) ... to make the 960 petals of the
1000-petalled crown center. Then another study begins, concerning 12 additional petals within the crown ...
