Forgiveness is the key to action and freedom.
The day the child realizes that all adults are imperfect, he becomes an adolescent; the day he forgives them, he becomes an adult; the day he forgives himself, he becomes wise...
The possible redemption from the predicament of irreversibility - of being unable to undo what one has done - is the faculty of forgiving. The remedy for unpredictability, for the chaotic uncertainty of the future, is contained in the faculty to make and keep promises. Both faculties depend upon plurality, on the presence and acting of others, for no man can forgive himself and no one can be bound by a promise made only to himself.
Without forgiveness there can be no future for a relationship between individuals or within and between nations.
Tagsforgiveness
If something in the exterior world makes you discontent, then it is not that object which troubles you, but rather your judgement of it; yet to blot out this judgement instantly is within your power. And if your dissatisfaction is based on the condition of your soul, who can prohibit you from correcting your views? Likewise, if you are discontent because you are not doing what seems reasonable to you, why not be active rather than discontent? "But something stronger than me is obstructing me." Still, do not be discontent; for the cause for your inaction is not within you. "But life has no meaning for me if this is not done." Well then, end your life, as calm as if you had succeeded; but don't forget to forgive your adversaries.
