OK, now I understand the kusala mula PS is not completely displayed.
What we don’t know: how is bhava defined in the last cycle with namarupa involved? It should not be kammabhava/upapattibhava, because the kamma is akaṇhaṃ asukkaṃ (neither dark nor bright).
Is there a complete kusala mula PS in the literature, in a commentary in the Tipitaka?
