釋禪波羅蜜次第法門 3.25

3.25

若繫心髮際，此處髮黑肉白，心則易住。或可發本骨觀，久則過生，眼好上瞻，或可見於黃、赤等色，如華如雲，種種相貌，令情慮顛倒。

If one ties the mind to the hairline, here the hair is black and the flesh is white, so the mind easily stays. It may also arouse one's original bone-notion contemplation; but over time faults arise, such that the eyes are fond of looking upward, or one might see colors such as yellow and red, resembling flowers or clouds, with various appearances that cause one's thoughts to become inverted.
