佛說觀佛三昧海經 1.50

1.50

"Having contemplated the mark of the hair, next contemplate the hairline, which is the color of red genuine pearls, gracefully hanging downward. It has five thousand lights distinctly intermingled, all inclining upward and surrounding the hairs, emerging from the crown and encircling the crown five times, like the painting of a heavenly artist, spherical, even, and as fine as a single silk thread. Between those threads various transformation Buddhas emerge, with transformation bodhisattvas as their retinue; all forms and images of the devas and the eight classes also appear within them, their colors like the sun disc, impossible to see fully. This is called contemplating the Buddha's hairline. Contemplating in this manner is called correct contemplation; contemplating otherwise is called erroneous contemplation." The Buddha addressed his father the king: "This is called the true contemplation of the Tathāgata's hairline."
