“Guru” means teacher, “yoga” means having knowledge or understanding of one’s own authentic state, the essential condition in which there is nothing to change or modify. We are not judging and thinking. This is the state of the guru. Guruyoga is, then, the main element in the practice of Dzogchen.
At times visualize at the hearth, at the center of a five-colored thigle a clear and luminous white A, energy of nonduality of the state of the guru and your rigpa. Otherwise, visualize a white A at the forehead in the middle of a gankhyil at the center of a triangle.
