The valleys of Oaxaca are the spiritual of the Mexico reserve, because in her tectonic depths beats the flowered heart of our ancient grandparents, those who dedicated their lives, generation after generation, searching for spiritual transcendence of existence.

.

"Oaxaca is the spiritual reserve of Mexico", because it is the depositary of the ancestral spirit force that comes from the very beginning of times and has been impregnated, not only in its monumental buildings, but primarily in the heart of the daily living of its people.

Oaxaca is the spiritual reserve of Mexico. Not only because its mountain ranges have been a natural wall against the invader and the foreign predator.

Or because the treasure of our most essential identity is kept in its bowels.

The Sierra Norte, known as La Sierra Juarez, is a mountain range that runs parallel to the Gulf of Mexico, from the State of Nuevo Leon and as it narrows forms the waist of the nation in Oaxaca, almost joins with the Sierra Sur, mountain chain which runs down from Alaska parallel to the Pacific Ocean and in Oaxaca is called "Mixtec knot".
