What Is an Art That Is a Tantra?

I often think that we're actually in an intensely sacred culture that pretends it isn't. That explains the strict moralism and almost sometimes fundamentalist approach to progressivism. We are a menace on all sides by premature ascenders who've tried to ascend before its time. An art should be able to help us go all the way down and not trapez there, but allow us to go back up whenever it's appropriate for us to do so as a completion of that downward movement.
