One cannot "visualize" the
formless. This is a logical absurdity;
to imagine necessarily denotes that one
forms mental
images. Rather, we should say that one may
conceive (understood in the etymological sense which meant simultaneous "coming into being" and "understanding" through intellectual intuition) of such, and this conception is made not
irrationally, but
supra-rationally. It is important to differentiate between genuine gnosis and the Romantic agnosticism (again, the etymological denotation is implied) that otherwise highly intelligent individuals fall prey to once they've exhausted the limits of understanding that the modern sciences almost universally afford, whether they be mathematical, linguistic, or physical sciences.
What we've hoped to have highlighted here are primarily 1) the need to prevent any further loss of knowledge that has arisen through the decay of language, and 2) a clear understanding of structure, which one has explained well
here.
