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".

Under the auspices of the Institute of graphic arts of Oaxaca, the library for the blind "Jorge Luis Borges" project has been developed, says Freddy Aguilar, especially since Oaxaca is a State with numerous cases of blindness and there is very little attention from the education authorities.

Visiting Monte Alban is opening a door to our immense and wonderful ancient cultural heritage. It is to go to the depths of our being.

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.
