From then on he began to write and teach about spiritual matters.
In the 1990s he published detailed descriptions of the major mystical traditions of the world, the synthesis of which he called Mysticosofia.
His aim was to show that all major mystical traditions seek, through various practices, to help a person advance via two major routes: the awakening of spiritual consciousness, and the creation of the body of light.
In 2014 he founded the ashram known as Casa de los Cuatro Rumbos (House of the Four Directions), near the city of Atlixco, Puebla, which offers courses and retreats.
He has published over fifty books.
