Based on Tibetan texts “Tathagata Vairochana sits at the center of the universe and also sits at the center of the Five Transcendental Buddha’s – the personification of the Five Wisdoms. In a cosmological system these are allocated five colors – white, blue, yellow, red, and, green – and the five elements – ether, water, earth, fire, and, air.
The Vairochana performs the dharmachakra mudra with both hands – the wheel of doctrine. A wedge shaped diamond points straight out of his head and represents the genuine truth”.
