	The Tree of Life

Ohr ("Light"; Hebrew: אור; pl. Oros Hebrew: אורות) is a concept in the Kabbalah (Jewish mysticism) and Hasidic philosophy. The analogy of light is used as a way of describing divine attributes. In particular, each Sefirah is said to consist of a light that comes to be vested into a vessel, or "kli" (Hebrew: כלי). Generally speaking, the light is simple and undifferentiated, as it stems originally from the Ohr Ein Sof, God's infinite light. It represents divine revelation in the world. It is associated with the Kabbalistic divine name of ban.

It is explained in Jewish Mysticism that Ohr is the revelation and expression of any particular spiritual level which descends from that level and enclothes itself in a vessel (Kli). This ohr is atypically in a state of nullification vis-a-vis the level from which it stems, and therefore, even when it descends to lower realms, posesses a desire toward Ratzu, a desire to go higher and return to its source. Correspondingly, the Kli is capable of persuading the Ohr to descend through its desire/understanding toward Shuv, an acknowledgment of the necessity of descent in order to fulfill the ultimate supernal will.
