Dallet (ד) means "door" and its shape resembles a humble person hanging on the doorpost, waiting for entry. It represents poverty, humility, and the act of receiving. Dalet is the portal through which one must pass to access higher states of being, requiring the lowliness of the ego. This letter's metaphysical meaning teaches that true entry into the spiritual mysteries begins with humility and an open, receptive heart, making it a door to divine knowledge.
