11 obstructions
to spiritual growth for a monk:
- There is the case where a monk is not well-versed in forms.
- He is unskilled in characteristics.
- There is the case where a monk acquiesces with an arisen thought of sensuality or to ill-will. He does not abandon it, dispel it, demolish it, or wipe it out of existence.
- There is the case where a monk, on seeing a form with the eye, grasps at themes or details by which — as he dwells without restraint over the faculty of the eye — evil, unskillful qualities such as greed or distress might assail him. Or he grasps through any of the other sense doors.
- There is the case where a monk does not teach others in detail the Dhamma as he has heard and mastered it.
- There is the case where a monk does not go time and again to the monks who are learned, well-versed in the tradition.
- There is the case where a monk, when the Dhamma-Vinaya proclaimed by the Tathagata is being taught, doesn’t gain knowledge of the meaning, doesn’t gain knowledge of the Dhamma, doesn’t gain joy connected with the Dhamma.
- There is the case where a monk does not discern, as it actually is, the noble eightfold path.
- There is the case where a monk does not discern, as they actually are, the Four Foundations of Mindfulness.
- There is the case where a monk — when faithful householders invite him to accepts gifts of cloth, alms food, lodgings, and medicinal requisites for curing the sick — knows no moderation in taking.
- There is the case where a monk shows no extra respect for the elder monks with seniority, who have been ordained long, who are leaders of the Community.
