Well theosis is always a personal thing, but we generally work on it within a community and as I said, only the most powerful, spiritually speaking, of monastics are allowed out alone. Maybe we are saying the same thing, but somehow I doubt it.
What I mean is, when God touches the soul it becomes an experience only those two can share. No one, no matter how well meaning, can understand the experience unless they have been there. Even then, there is only a limited amount an elder can do beyond spiritual direction. The journey can be very lonely even within a group. I think that is part of the process. God wants us to rely solely on Him instead of human resources.
