1.56

"At that time Yaśodharā's father extended the Prince's white hair with his hand. He saw that the white hair was like a crystal banner, with joint corresponding to joint, and between the joints he saw immeasurable hundreds of thousands of Brahmā kings and Śakra Devendra, along with various supreme devaputras and their palaces, seen with complete clarity, just like seeing the image of one's own face in a bright mirror. Having seen it, he was filled with joy, and immediately released it. As before, it curled to the right and returned to rest between the eyebrows, its brilliant light radiant and blazing, scattering across the four quarters and entering into the contours beyond full description. This is called the mark of the white curl at the time of the Bodhisattva taking a consort."
