The first Hebrew letter - Aleph à – is a symbol in Kabbalah for non-dual Oneness.

This Aleph embedded in a circle represents the Unification of Opposites – like the Chinese yin/yang symbol. Its upper red part (Yod) with vertical lines represents Fire or Heaven, its lower blue part (inverted Yod) with horizontal lines represents Water or Earth.

The middle yellow part (Vav) with diagonal lines represents the Breath or the Air that unites Heaven and Earth, and shows that they are Not-two.
