user-1: I found the text below on another site. However, it doesn't say whether the source is a specific sutta, commentaries or something else. Could someone show me the origin?

Six things are conducive to the abandonment of restlessness and remorse:

Knowledge of the Buddhist scriptures (Doctrine and Discipline);
Asking questions about them;
Familiarity with the Vinaya (the Code of Monastic Discipline, and for lay followers, with the principles of moral conduct);
Association with those mature in age and experience, who possess dignity, restraint and calm;
Noble friendship;
Suitable conversation.

user18: It is most likely taken from the commentary to the satipatthana sutta, which has a similar list for each of the five hindrances. They are all worth reading:
