Re: Books that changed the world
I found it similar to Kama Sutra as Kama Sutra is a how-to-manual for all aspects of life from priorities of life, acquiring knowledge, good conduct to acquiring a wife, etc. As far I remember the content of Behashti Zevar, it also deals with connected issues like how to be a Naik Parveen Bibi bearing all the bad from husband and remain contend (sabir o shakir) on the presumption that such behavior will win heart of the husband.
Basically both books seems to cover ways how to appease spouses.
