What is it in you that brings you to a spiritual teacher in the first place? It's not the spirit in you since that is already enlightened and has no need to seek. No it is the ego in you that brings you to a teacher.
Absolutely the worst thing about this job is the travel and being away from family. I have a wife and three wonderful children the kids are all active in sports and it's very difficult to up and leave and miss them growing up.
