瑜伽師地論略纂 2.50

2.50

In the progressive enumeration of matter, "light with support" is light with physical substance; "light without support" is light detached from physical substance. Alternatively, light attached to physical substance is called with support; light distant from physical substance is called without support. "Regular and irregular light" refers to the waxing and waning light of the sun and moon and the like. "Accumulated matter" refers to the various shapes. Among the nine kinds, internal and external are not mentioned; even if one's own body and another's body are external bases, they are definitely spoken of separately from the faculties, yet are actually similar. Sound has only two natures; unwholesome and veiled-unrecorded ones are so named because they are generated by that volition. The Prakaraṇa says: the conventional manifest [action] extends to wholesome and unwholesome, but its real entity does not. The former form realm is also like this.
