瑜伽師地論略纂 8.25

8.25

論答於經行時從幾障法修其心中云「以有明俱心及有光俱心」者，謂水火、星月、藥草、珠寶是明，緣此明之心，名明俱心；唯日一種是光，緣此光心，名光俱心。以日能發光，隱蔽處而令見，餘月等不爾。

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.
