He is totally unique in all existence. Rather all flow from a unified purpose and existence. Aleph is related to the Hebrew word aluph , which means master, chief or prince. The numerical value of the three letters that compose the Aleph is twenty six. He was, He is and He will be.
Aleph is the only silent letter because it represents the unrevealed, infinite spiritual.
The Aleph also represents the channel of the spiritual, heaven, to the physical, earth, which is symbolized by the second Hebrew letter, Beit . This is one of the reasons why it's the first letter. The form of the Aleph also symbolizes this. The upper Yud represents the spiritual world and the lower Yud , the material world. The Vav in between is the conduit that links the two together.
