Also Fulcanelli is available in Spanish: "Las moradas filosofales", "El misterio de las catedrales".
Some books by Mircea Eliade are available in Spanish.
Louise Hay, "Usted puede sanar su vida" is also interesting.
All of Castaneda's books are available in Spanish: "El lado activo del infinito", etc (we don't recommend all of them though).
