Make not the living thy foe, nor take weak vengeance of the dead.
For life is as a game of chess, where least causeth greatest,
And an ill move bringeth loss, and a pawn may ensure victory.
Dost thou suspect? seek out certainty: for now, by self-inflicted pain,
Or ill-directed wrath, thou wrongest thyself or thy neighbour:
Suspicion is an early lesson, taught in the school of experience,
Neither shalt thou easily unlearn it, though charity ply thee with her preaching;
Yet look thou well for reasons, or ever mistrust hath marred thee,
Or fear curdled thy blood, or jealousy goaded thee to madness;
For a look, or a word, or an act, may be taken well or ill
