Why get excited over these small things or let them disturb you? If you remain quiet, things will go much better and, if there is any difficulty, you are more likely to find out a way in a quiet mind open to the Peace and Power. That is the secret of going on, not to allow things and happenings, not even real mistakes, to upset you, but to remain very quiet, confiding in the Power to lead you and set things more and more right. If one does that, then things do get actually more and more right and even the difficulties and mistakes become means for learning and steps towards progress.
Do not allow yourself to be worried or upset by small things. Look at things from an inner point of view and try to get the benefit of all that happens. If you make a mistake, don’t get distressed because you made a mistake—rather profit by it to see the reason so as to get the right movement in future. This you can do only if you look at it quietly from the inner being without sorrow or disturbance.
