LMA, you are woefully ignorant of MO thought process and philosophy. Who says MO people don’t believe in mystical aspects of mitzvos? Why does that mean they don’t perform mitzvos because Hashem commanded them? That is WHY we keep mitzvos. We would even if there were no kabbalistic reason.
And why would a woman not want to rely on her husband’s learning? Would you rely on paying someone else to do mitzvos for you? Especially if it helps you connect to Hashem?
