The path of influence from Arich Anpin to Zeir and Nukva.
The full path of influence: A"A → Abba and Imma → Zeir Anpin (Z"A) and Nukva. The path's form-changes-at-each-level — the gradation that brings cosmic mercy to operational service.
Op. 114 closes the Abba and Imma unit by tracing the full path of influence from A"A to Z"N. The chapter is structural — it specifies the cosmic-operational chain by which A"A's interior mercy reaches the deed-relevant level.
A"A's interior holds complete Kindness (Op. 91). The path of influence carries this Kindness downward through:
A"A's Beard (Op. 105–108) — the thirteen Tikkunim, the operational channels.
Abba and Imma (Op. 110–113) — the parental Partzufim that transmit Concealed Wisdom through CHaDaR; constant coupling as the standing root.
Z"A and Nukva (Op. 115–138) — the operational pair; the immediate cause of the lower creations.
The path's form changes at each level. At A"A, the influence is complete Kindness. At the Beard, it becomes thirteen-fold mercy in CHaDaR. At Abba and Imma, it becomes Mental Powers transmitted as whole-and-detail. At Z"A, it becomes CHaDaR governance through the body. At Nukva, it becomes operational distribution to the lower creations. Each transformation is required by the law of gradation (Op. 44) — the cosmic mercy must take the form suitable for its receivers at each level.
Op. 115–138 will operationalise the path's terminal segments. The closing chapters' Coupling-order doctrine is the path's operational completion.
