大方廣佛華嚴經疏 37.11

37.11

1. Explaining the name: "Bodhi" is awakening, and "factor" (pakṣa) has the meaning of cause; these thirty-seven are the causes of awakening for the various vehicles. They are also called the categories of the path (mārgāṅga): "categories" (pin) means classes, because the causes belong to the class of the fruit. The distinct names will become apparent in the text itself.
