Telos

I have fasted,
I have drunk the cup;
I have received from the box;
having done, I put it into the basket,
and out of the basket into the chest."

Elusinian mysteries -
Clement of Alexandria, Protreptikos

'Telos', a Greek word meaning consummation.

Mystic, a word with Greek etymology, derived from 'mustein', close lipped.

I'd post this video right here if I could.
