What led him to seek out those ascetic practices. That is what I was getting at. What was it that his father attempted to shield him from based on the prophecies?
I'd say forget all that nonsense about father and this or that. Use common sense instead. Ask the question what makes anyone search out truth and thus enter ascetic practices and spiritual disciplines. Seeing life don't make sense that's what. Seeing it don't make sense and wondering what it's all about and why they are here.
Different circumstances in life can lead to a person doing this but no one can make them. It's always personal.
Violence is not natural but unfortunately can be considered normal.
