"There were the physical challenges of hitchhiking across Turkey, Iran, Afghanistan, and Pakistan as they were quite dangerous areas. I wrote about that in The Journey Home. I loved my family and they loved me, so making a choice so completely different from the life they knew was also a challenge. Not having material possessions or the security of a home and taking vows of celibacy for life were kind of natural for me, although they were also challenging. But I guess the greatest challenge for me was that I loved so many different spiritual paths."
