The proposition consists of four parts. Part 1: The Line of Eyn Sof... This explains how the Line extends within the Residue. Part 2: Yet it stands outside… This explains the Encompassing Light. Part 3: Even so... This explains how the Line accommodates itself to match the Residue into which it enters. Part 4: This is the Inner and Encompassing Light... This explains the different aspects of the spreading light and their names.
Part 1: The Line of Eyn Sof, blessed be He, that entered into the Residue is concealed within it on the inside on all its levels... The concealment of the light of the Line of Eyn Sof within the Residue is the source of the two modes of government discussed earlier: the rule of good and evil and the rule of unity, corresponding respectively to the Form of Address and the Name. The rule of unity is concealed within the manifest rule of good and evil. Accordingly, we say that the Line is concealed. And this is what was gained through having the Line clothe itself within the Residue.
