What is illuminity?

Answer 1

Not sure what you mean by "illuminity", however both the terms "illuminati" and "illumination" are frequently encountered in searches on philosophy and religion.

Illumination is a subjective experience where one "becomes aware" of the mystical/supernatural/divine, usually to the extent that the physical world is illusion and that there is a deeper level of reality in which truth/meaning/purpose can be discovered.

The Illuminati is also fairly hard to define. First, because there have been hundreds of groups calling themselves the Illuminati (or some similar term), secondly because most information about them is found only in materials on conspiracy theories (the Illuminati are one of the many "secret" groups who are supposedly in charge of the world). However, historically, most groups have taught Libertarian ideals of equality and community, minimal influence by government or organized religion, and general "enlightment" philosophy.
