Abba and Imma — spread of the Concealed Wisdom in the columns of Kindness-Judgment-Mercy via the Beard for Zeir Anpin.
Abba and Imma transmit Concealed Wisdom through CHaDaR via A"A's Beard, downward toward Z"A.
Op. 111 names the operational role of Abba and Imma. They transmit Concealed Wisdom — the cosmic-mental content that A"A's interior holds — through the three-column structure (CHaDaR), via the Beard's channels, downward to Z"A.
Abba and Imma are not just the parental Partzufim in a generic sense. They have a specific operational task: transmission. The cosmic-mental content (Concealed Wisdom) needs to descend from A"A's interior to Z"A's operational anatomy without losing its structural identity. Abba and Imma are the Partzuf-couple that performs this descent.
Through CHaDaR via the Beard: the three-column structure is the operational form; the Beard's thirteen Tikkunim are the operational channels. Abba and Imma use both as their transmission apparatus.
The operational consequence: Z"A's Mental Powers — Chochmah, Binah, Daat — come from Abba and Imma's transmission. Without Abba-Imma's role, Z"A would have no Mental Powers; without Mental Powers, Z"A's CHaDaR governance would be impossible.
Op. 124 (Daat as the offspring of Abba-Imma engrafting via Chochmah and Binah). Op. 116 (Abba and Imma direct Z"A through his Mental Powers).
