The connection between AV (gematria 72), SaG (gematria 63), MaH (gematria 45) and BaN (gematria 52) and their place of emergence from Adam Kadmon's sensory organs.
AV, SaG, MaH, BaN emerge from AK's eyes, ears, forehead, and mouth respectively. The connections become koneniyut — the cosmic clock-mechanism — by which Partzufim couple.
Op. 32 introduced AK's radiations; Op. 34 specifies which expansion emerges from which organ. The chapter also introduces the apertures — the points at which the radiations meet between cosmic levels — which become the cosmogonic seed of koneniyut, the inter-Partzuf coupling mechanism.
Four expansions, four organs. AV (from the eyes — sometimes the head): the active, primary expansion. SaG (from the ears): the receptive-yet-active counterpart. MaH (from the forehead): the Forehead expansion that becomes the source of the new MaH after the breaking (Op. 54). BaN (from the mouth, or the eyes in another aspect): the receptive expansion that becomes the Residue of the cosmogonic process.
The apertures (nekavim) at which these radiations emerge are structural points where the upper level meets the lower level. The connections through these apertures are not just emanations from the upper level; they are couplings between levels. When the cosmogonic process unfolds, these apertures become operational coupling points — the cosmic-mechanical structures by which the upper Partzufim direct the lower ones.
This is the cosmogonic seed of koneniyut — the doctrine Op. 70 names formally with reference to Daat Tevunot p. 101: like a clock whose wheels meet and one small wheel moves many great wheels. The apertures Op. 34 introduces at the AK level become the structural rule for every later inter-Partzuf coupling.
