I'm reading an article in which the author writes about his experience of walking a pilgrimage route. And it goes:
"Everybody got lost now and then. I don’t know that it’s an inevitable part of any pilgrimage, although I can see where it might be. I do know it was part of ours."
Does "I don’t know that it’s an inevitable part of any pilgrimage" mean that "I don't know if every pilgrim gets lost on the way"? If so, what does he mean by "although I can see where it might be"? I'm at a complete loss of understanding this sentence.
