Lammed (ל) is the tallest letter, symbolizing a "goad" or a heart reaching upward toward the divine. It represents learning, teaching, and the aspiration of the heart to transcend its limitations. Lamed's form rises above all other letters, indicating a state of elevated consciousness. In the Hermetic tradition, it signifies the striving of the lower self to unite with the higher self, making it the heart of all spiritual pursuit and the core of inner alchemy.
