Think first -“Health- I’d question that sefer, from what I’ve learned from my rebeim is that all neshamos are gilgulim today.”
And there are those that question whether there even is such a thing as Gilgul. (Reshash)
But the source is a Choshuve Sefer. It’s not my fault that you & your Rebbeyim never heard of this. The more you learn -the more you know.
1. It’s a Machlokes whether there is such a thing as Gilgul.
2. One Sefer says this (Gilgul) applies only to men. I haven’t heard anybody say it applies to women. Saying e/o is a Gilgul – can just mean whomever this can apply to; namely men, not women!
