For every function and for each effect there are two generators through the coupling of male and female — Kindness and Judgment.
Every cosmic function has two generators — male and female, MaH (gematria 45) and BaN (gematria 52), Kindness and Judgment. The two-generators principle runs through every later coupling.
Op. 63 names the two-generators principle — every cosmic function and every cosmic effect requires the coupling of two partners. The chapter cites Niddah 31a (woman emits red seed), the rabbinic teaching on shared-cosmic-generation that anchors the principle.
The Talmudic teaching: in human conception, both partners contribute. Niddah 31a says the woman emits red seed (the menstrual matter that, in the rabbinic embryology, contributes the body's flesh) and the man emits white seed (contributing the bones, sinew, and other firm structures). Both contributions are structurally distinct and structurally required.
Klach reads this cosmogonically. Every cosmic function — every effect that the cosmic government produces — requires two generators. One contributes the active aspect (Kindness, MaH, masculine); the other contributes the receptive-yet-shaping aspect (Judgment, BaN, feminine). Without both, no cosmic effect emerges.
The mind-thought analogy: a thought is generated by the mind but expressed only through language — and language is shaped by the receiver who must understand it. Mind and language are two generators; thought is their coupled offspring. The cosmic government operates by the same logic at every level.
