Agustín and Paloma, our tireless promoters of applied and practical spiritual ecology and their recently formed group "Don Uriel" join various groups of seasoned walkers in the sacred city of Teotihuacán to perform an important ritual-walk during the Autumn equinox. The solid group of walkers, candidates to become spiritual warriors would try to establish the necessary tuning with the pyramid of the Sun, which thanks to the recent work of a group of Tibetan spiritual warriors sent by his holiness the XIV Dalai Lama, had been "activated" and was now capable to distribute to all those who knew how to contact it with respect, honesty and purity, the powerful energy coming from the cosmos that the pyramid was destined to transmute and redistribute for the benefit of individuals and of all the nadis and energetic centres of the enormous Mexican chakra that was active, functioning and contributing to awaken its sacred territory.
