For as we can get into the fearful state of constantly recalling all who have ever vexed or wronged us, or nursing the memory of what we hate or despise, until our minds are like sewers or charnel-houses of dead and poisonous things, so we can resolutely banish them, at first by forethought, then by suggestion, and finally by waking will.

And verily there are few people living who would not be the better for such exercise.

Many there are who say that they would fain forget and be serene, yet cannot.

I do not believe this.

We can all exorcise our devils--all of them--if we _will_.
_To restrain irritability in our intercourse with others_.
