As the full meaning of reincarnation and of karma sinks deeper and deeper into his mind, a generous tolerance will rise higher and higher in his feelings. He will begin to see that every wrong-doer is what he is because of his past experience and present mentality and has to act in the way he does and cannot act in any other way...
When the actions or words of others provoke us, it is easy to become irritable, resentful, or indignant; it is hard to practise a bland patience and exercise a philosophic tolerance. But that is just what the aspirant must do.
One shouldn't brood over fancied wrongs which he believes have been done to him nor dwell on another's faults. The law of recompense will deal with the situation. Emotional bitterness is harmful to both persons. On this path, the student must learn to overcome such feelings; they act as obstacles which hinder his advancement.
Ordinarily it is not easy, not natural, to forgive anyone who has wronged us. The capacity to do so will come to us as understanding grows large enough or as meditation penetrates deep enough or as grace blesses us.
