Part 1. RABASH "Purpose of Society - 2"

Part 2: Concepts in the structure of the worlds

1) Ein Sof

The first discernment is the form of this entire reality as it is prior to the restriction. At that time, everything was without a boundary and without an end. This discernment is called “the light of Ein Sof.”

(Baal HaSulam/Study of the Ten Sefirot/Vol. 1/Part 1, Inner Observation, p.5)

2) What is the name “Ein Sof?”

Before the restriction, the name Ein Sof implies that there is no Sof or Sium (end) there whatsoever, since phase four receives the light as well. Thus, in that place there is no reason to stop the light and form a Sof and Sium.
