since places where many people gather cause distraction, one fails in what one has to do;
since taking pleasure in drowsiness, sluggishness, and idleness prevents one from completing any work, it is a false friend;
since exultation and self-reproach disturb the mind, they hinder a wider perspective;
since many people and acquaintances are an occasion for much involvement, attachment, and aversion, they counteract concentration;
since talkativeness diminishes any feeling of wholesomeness, hinders its arising, it is a source for dissatisfaction and strife.
It is by giving up all these hindrances that meditative experiences will naturally grow, and that one perseveres in the teachings of the Victorious One.
