PBA – it’s a special thing for women to be able to get the schar of Limud Torah by enabling others to learn. A teacher of mine once showed me a Gemara or a Rashi on a Gemara (I have no idea where it was – maybe someone here can help out?) to the effect that when a lady does housework so that her husband and sons can learn it counts as Limud Torah for her. This is something specific to women.
I have no idea if I’m quoting correctly at all, so if someone knows the source, I’d appreciate it.
