Since the Twelfth Century, people in the Kagyu tradition of Tibetan Buddhism have revered the Karmapas as spiritual leaders. The Sixteenth incarnation, H.H. Rangjung Rigpe Dorje, saw this flag in a dream. He called it Namkhyen Gyaldar, "Victorious Flag of the Buddha's Wisdom", and announced that "wherever this banner is flown, the Dharma will flourish." The sky blue color represents the complete and profound Wisdom of the inner realization of the Buddha. The yellow color on the flag represents the complete Wisdom of limitless Compassion which bestows benefits on all sentient beings and phenomena. The wavy line and the joining of the yellow and blue colours signify the inseparability of these two Wisdoms.
