Guhyasamaja, in the form of the United Pair, blazes in the glory of the wondrous signs and marks, with a divine compassion that understands perfectly the emptiness of self, of all beings, and of all phenomena. The complete form of this image represents the very highest levels of practice and very subtlest states of mind; the depth and complexity of the path that the yogi or yogini traverses to reach them; and the unsurpassed elucidation of this path by the King of Dharma himself, Lama Tsongkapa (1357-1419).
