Lust, or more traditionally Strength is associated with the Hebrew letter Teth. Teth means serpent and ennumerates equally in the system of Kabbalah with the word for messiah.

Lust is also associated with Leo, the sign which is the very epitome of energy and life. It is also worth noting that 11 is considered the number of magick by Aleister Crowley.
