Twenty defects of distraction

The Sutra That Admonishes One to Superior Intention says:

Maitreya, there are twenty defects of distraction. What are these twenty? Maitreya, they are:

1. not to have controlled your body,
2. not to have controlled your speech,
3. not to have controlled your mind,
4. to have great desire,
5. to have great hatred,
6. to have great dullness,
7. to be tainted by mundane conversations,
8. to have completely strayed away from supramundane conversation,
9. to associate with people who do not respect the dharma,
10. to have fully cast away the dharma,
11. to consequently be harmed by the maras,
12. to associate with people who are careless,
13. to be careless oneself,
14. to be dominated by conception and discernment,
15. to completely stray away from great learning,
16. to fail to achieve shamatha and vipashyana,
17. to fail to quickly maintain pure conduct,
18. to completely stray away from rejoicing in the Buddha,,
19. to completely stray away from rejoicing in the Dharma, and
20. to completely stray away from rejoicing in the Sangha.

Maitreya, understand that these twenty defects are the defects of taking delight in distraction. A bodhisattva after having applied examination will take delight in solitude and never become completely disheartened.
