In the story of Purim, the מדריש says that Haman made a פור to decide what month he should chose, in it, he took into account the מזל of the month etc. My question is, what role does מזל play in life? I have heard people say that it doesn’t apply to the Jewish people, so what is the purpose? Does it only apply to the other nations? If so, how does that fit in with the concept of free will? Why should your birth month make a difference to how one acts?
