Repugnant, foul, unworthy, not valuable, best gotten rid of. The associations we have with this substance correlate well with the counter-Divine Will basis on which it's symbolically used. Of course those Choosing a counter-Divine Will basis tend to disregard those connotations and merely regard it symbolically, applying 'inversion' to the concept because they're actively seeking the gains provided by the organization for being on such a basis.
Through derivative symbolism we also get [post█rior] and from it, [cha█r] which are also used. The royal [thr█ne] is one special application of this concept: it appears to represent overt command and supreme earthly authority, but is both a counter-Divine Will representational symbol and even overtly rather déclassé and disrespectful a set of imagery to impose upon ostensibly-respected public figures who are at least presented as being superior to the common man. Regarding him as being just as mundanely human as any of us rather tends to disrupt the ill█sion, which is part of the idea: authority limited, and rather easily, due to his counter-Divine Will basis. Pomp which can be revoked at any time.
Special usage: There is another special 'use case' we must address with the derivatives of this symbol, that of the [empty cha█r]. Readers will recall that the Babylonian Kabbalists purport to use counter-Divine Will symbols as ostensible 'inversion' symbols, on the implied basis that, 'We would never actually ourselves adopt a counter-Divine Will basis, not at all', manifest organizational results to the contrary. So when they deploy the symbolism of an [empty cha█r] the common usage is to supposedly 'invert' the concept of 'empty' to 'occupied' and symbolically reference someone as having accepted a counter-Divine Will basis. Its antonym would ostensibly be an [occupied cha█r]. It all of course presupposes the acceptance of using counter-Divine Will symbolism as an acceptable custom, and that its meaning can merely be 'inverted' with no problems. It also requires that the message's translators keep well aware of what supposed 'inversion' mode of symbolism is being deployed, in order to get an accurate translation.
I suppose we must also, regrettably, consider the symbolic implications of the trending phrase, "B█llsh█t". Elsewhere we've established that symbolically the [b█ll] is [Ta█rus] is the idol B██l to the Babylonian Kabbalists, and we've now seen how the sec█nd part of this compound word is symbolically used. Together, it appears to reference efforts to get someone to accept a counter-Divine Will basis, a sort of 'inversion' of the f██d symbol.
