Ein Sof
Kabbalists call their God “Ein Sof,” which means “the infinite.” Ein Sof exists everywhere in the form of energy. Though its presence and power are infinite, Ein Sof remains a distant unknowable God, entirely devoid of form. Kabbalists all aim to reunite with God by restoring Ein Sof to its original form through righteous acts and devout study of Kabbalah
AYIN
Nothingness. When Ein Sof began to create the universe, it had to make yesh, (something) out of ayin (nothing). Before Ein Sof created the universe, only ayin existed.
