In the Talmud Yerushalmi it is brought that every word of Torah is worth as much as all the other commandments. But to realize this truth is not always open to everyone. I for one, tasted the "taste of Torah". So I thought to devote myself to learning Torah always. But to do so clearly one needs to marry the daughter of a authentic Litvak Torah Scholar [that goes by the Gra]
The reason the sages recommend to marry the daughter of a Torah scholar is that daughters of amei haaretz [people ignorant of Torah] are hostile to Torah. They will do almost anything to stop their husbands from learning Torah. They might say it is "for parnasah", [they want their husbands to work],but that is just a cover story for public consumption. They really just do not want to see their husband sitting and learning Torah--even if they would already have plenty of money.
In some cases however, to marry a bat talmid chacham [daughter of a Torah scholar] is not possible.
Part of the reason is phony Torah scholars תלמידי חכמים שדיים יהודאיים Torah scholars from the Dark Side. So one might be offered a shiduch of the Dark Side. [Or a baalat mum, a girl with a hidden defect.]
