Ohr Ein Sof: Infinite Light
Shefa and Ohr (1)
Ayin Beis Volume 1, Discourse 14, Shoftim, Chapter 53 p. 94-96
Short Summary: Ohr ein sof means that the energy itself is infinite. We can understand this by examining the difference between shefa (flow) and ohr (light), with shefa being an emission of substance that creates a change and effects its source, and requires investment.
