When I was in Yeshiva many years ago I heard one of the rebbeim (teachers) of the yeshiva speaking to a young man that had converted to Judaism and that was very successful in learning about "his status" in regards to certain halachos (that perhaps might not be nohag now a days) and how a convert is different.
One of the things the Rabbi said was that "you should know the Ari Zal writes that the neshemas (souls) of a convert comes from the 'highest places' in Shamayim." Now I realize this hard to perhaps understand what a soul coming from a high place really means but it was meant to show how "special" this person really is.
Is it known where this is brought down from the Ari Zal or in any other sifrei kabballah or sefer at all?
