"I Was Very Taken Aback"
I have another friend who is a convert and a chasid. He said that the first time he picked up a particular sefer he soon read a comment about the Umos haOlam's which was difficult to take....and put the sefer down for several years in protest. Only later did he learn context which helped him assimilate the concept.
