Tau, the last
letter of the Hebrew alphabet represents the culmination of all manifestation,
the culmination of the process started in daleth, continued in
mem and resulting in tau.
That the tau is
mankind's final destination is demonstrated by the word
(emet, truth). This describes the entirety of the journey from the
archetypal life essence in aleph through to perfection in tau.
That this journey is exemplified by the word for "truth" demonstrates the
fundamental nature of this quality (see pe for a consideration of "lying").
