This teaching has been around for centuries in Mexico and went underground on the arrival of the Spanish into Mexico. It has subsequently been passed down from generation to generation until emerging in the late sixties with the writings of Carlos Castaneda and more recently with Don Miguel Ruiz who received the teaching from his mother and grandmother. Don Luis was apprenticed by Don Miguel for many years and in 1992 Don Miguel initiated him to carry the ancient teaching of the Toltecs.
