Yod (י) is the smallest letter, depicted as a mere point or flash of insight. It represents the divine spark, the primordial point from which all creation emanates. Every other letter contains the essence of Yod. It symbolizes the hand of God, humility, and the seed of potential. In esoteric knowledge, to contemplate Yod is to connect with the infinitesimal point of infinite power within oneself, the source of all consciousness expansion and the foundation of the entire universe.
