Avidya

Ignorance, the neglect of the real. A vehicle of deliberate exclusion.

The Vehicle of Ignorance has been used by all the great sages of antiquity.
From confidence game to esoteric teaching,
ignorance has been the central and most valuable aspect and feature
of every form of human mysticism,
its beauty and perfection misjudged and mischaracterized
when it has begun to mingle deftly with the knowledge
of those who unwittingly worship it.
