NOTHINGNESS & ABSOLUTE ALL
Based on Kabbalistic texts, God, as the genesis of all things, is hidden in infinity, "Ein Sof" in Hebrew.
According to this interpretation, the infinity of God is without limitation, boundary or quantity. It is, in essence, outside of human conceptual ability.
According to the Kabbalah, 'Ein Sof' is in everything. Yet in the creation process, God created the hidden realms, so the God concept itself is invisible to human consciousness. Only in the highest spiritual realms does the light of Ein Sof have direct impact.
