瑜伽師地論略纂 8.25

8.25

Where the treatise answers how many hindrances one cultivates the mind against during walking meditation, saying, "With a mind accompanied by brightness and a mind accompanied by radiance": water, fire, stars, the moon, medicinal herbs, and jewels are "brightness"; the mind that takes this brightness as an object is called a "mind accompanied by brightness." The sun alone is "radiance"; the mind that takes this radiance as an object is called a "mind accompanied by radiance." Because the sun can emit light that causes obscured places to be seen, whereas the moon and others cannot do so.
