Wisdom Teachings - Sat Yoga, Costa Rica

Student Question:  Can you please talk about what I would call the "art of replacing yourself?"  There is a book that you gave me a long time ago which talks about creating community and it spoke of this.  It specifically mentioned the necessity of replacing oneself as one of the final steps of sustainability.  Usually the ego wants to be special and hold on to its specialness and be the only one that can do something, which gives it some sort of power.  So I was thinking about this and was hoping you could talk about this?
