For instance, in meditation restlessness is often the impatience to move quickly on to the next stage. The fastest progress, though is achieved by those who are content with the stage they are on now. It is the deepening of that contentment that ripens into the next stage. So be careful of 'wanting to get on with it' and instead learn how to rest in appreciative contentment. That way, the 'doing' disappears and the meditation blossoms.
Remorse refers to a specific type of restlessness which is the kammic effect of one's misdeeds.
The only way to overcome remorse, the restlessness of a bad conscience, is to purify one's virtue and become kind, wise and gentle. It is virtually impossible for the immoral or the self indulgent to make deep progress in meditation. Doubt refers to the disturbing inner questions at a time when one should be silently moving deeper. It should be remembered that such questions are obstacles to meditation because they are asked at the wrong time and thus become an intrusion, obscuring one's clarity. The Lord Buddha likened doubt to being lost in a desert, not recognising any landmarks.
