The resolution of the apparent contradiction is as follows: The channeling of BaN is through the Nukva, but when it comes to the repair and selection of the parts that ascend, the Male also enters into this, for the Male repairs the right side while the Nukva repairs the left.
And afterwards the parts join up together... And the reason is in order to repair the Kindness-Judgment-Mercy they contain, which was not repaired at first and needs to be arranged in them through the respective roots involved – Kindness through Abba, Judgment through Imma, and Mercy through Understanding, which produces connection. This was not necessary in the case of MaH, which had already emerged from the roots in a proper state of repair arranged in the mystery of three columns.
