BECOME A MENTOR TO A PRISONER INTERESTED IN BUDDHISM
The Greater Boston Zen Center encourages experienced practioners to mentor a prisoner interested in Buddhism by postal mail. The easiest way to do this is through an independent organization called Dharma Companions. The program at GBZC is coordinated by Kate Hartland, and she is available to talk with you regarding her experience of the program, and to consult with when corresponding with prisoners.
Email Kate for details.
