(Yoga-sūtras: 2.33–34)
“When obstruction from adverse inclinations occurs, contemplation of obstacles [is to be cultivated]. ||33||
“Adverse inclinations are harming (hiṁsā) and so forth [i.e., lying, stealing, fornicating, and accumulating in excess, that is, acts that contravene each of the five aforementioned yamas] which are [either] enacted, caused to be enacted, or assented to, and which are preceded either by greed, anger, or delusion, with each of these [preceding causes] being either mild, moderate, or intense. ‘These the unending results of which are hardship and ignorance’ is contemplation of obstacles [i.e., the obstacles created by acting upon the aforesaid adverse inclinations are to be contemplated to preclude one from acting upon them]. ||34||”
