In Kabbalistic and Hasidic philosophy, seder hishtalshelus or hishtalshelut (Hebrew: סדר השתלשלות) refers to the chain-like descent of spiritual worlds (Olam/Olamot) between God and Creation. Each spiritual world denotes a complete realm of existence, resulting from its general proximity or distance to Divine revelation. Each realm is also a form of consciousness reflected in this world through the psychology of the soul.
