瑜伽師地論略纂 6.13

6.13

Ninth, in explaining the sūtra on the bhikṣu of pure mental practice contemplating the five characteristics, the text has five parts: first, citing the sūtra to mark it; second, explaining pure practice; third, clarifying the hindrances to practice; fourth, separately explaining contemplation of the five characteristics; fifth, the conclusion. 'Hindrances' refers to unwholesome thoughts of sensuality, malice, and harming; thoughts of kin, country, and non-death; and thoughts of past pleasures and the like. These seven kinds of discursive thoughts (vitarka) all constitute the essence of hindrances.
