How can Shlomo write in Mishlei 1:8b, וְאַל-תִּטֹּשׁ, תּוֹרַת אִמֶּךָ, "don't abandon the Torah of your mother" if the Mitzvah of teaching one's sons - וללמדו תורה אבל לא האם - and learning Torah - ותלמוד תורה - and the Mitzva of having children - פריה ורביה - are exemptions or optional for a woman?
I understand that one can also take "Torah" in this passage to mean "Minhag" or whatever Remez/Drash/Sod it can mean, but my question is simply in the Pshat level of Mishlei 1:8b, וְאַל-תִּטֹּשׁ, תּוֹרַת אִמֶּךָ
This question grew out of the answer of Danny Schoemann in the discussion here: In how many of the 613 mitzvot are women obligated?
