At the website link below you can order the little book by Aivihdi Waya, Soul Recovery & Extraction. It is highly recommended to prepare you for soul retrieval or extraction with Mikkal, written by his teacher, with excellent examples from people who have experienced SR/E.

You can also order an excellent shamanic drumming CD produced by my shaman-clan brother, Gary Gent, also a Cherokee-metis, and brother of Ai Gvhdi Waya. It is Called Mother-Drum Journeys
