Hei (ה) represents divine revelation, breath, and expression. Its sound is a mere exhalation, symbolizing the gift of life from God and the power of speech to create and destroy. In scripture, God adds a He to Abram and Sarai's names, transforming their identity and destiny. As a window, it allows light in and out. In Jewish mysticism, He is the vessel through which the seed of thought is actualized, making it crucial for manifesting intention and experiencing spiritual awakening.
