Commentary by Pir-o-Murshid Inayat Khan
It is to the great disadvantage of the fault-finding man that he wishes to find fault with all he sees, for if he is not able to throw away immediately the undesirable impression received, which is not always so easy, he begins in due time to reproduce what he has received. ... If man only knew what harm is brought to one's being by letting any undesirable impression enter the heart, he also would adopt the above-mentioned policy of the wise, to overlook.

Those who trouble about others' thoughts and interest themselves in others' actions most often lose their time and blunt their inner sight. Those who go farther, their moral is to overlook all they see on their way, as their mind is fixed on the goal. ... The best thing is to see and rise above, never to halt on the way, and it is this attitude that, if constantly practiced, will lead man safely to his soul's desired goal.
