As a student that had the opportunity to study and be with Alberto Villoldo and his wife Marcela in both Peru and Chile, I have the greatest respect for  Alberto in his ability  to introduce and educate the west with the ancient healing practices of the The Laika, high Shamans of the Q’ero lineage.  His collection of books are all wonderful and his knowledge is shared with the permission of his Indigenous Shaman Mentors and friends.
