Developing concern for others, thinking of them as part of us, brings self-confidence , reduces our sense of suspicion and mistrust, and enables us to develop a calm mind.
Cultivating care and concern for others gives rise to a kind of inner strength. No matter what difficulties or problems you face, in this wider context they’ll seem less significant and troubling to you. The inner strength, self-confidence and courage you gain by focussing on others’ needs instead of your own, brings with it a deep, calm sense of satisfaction.
Each of you should feel that you have great potential and that, with self-confidence and a little more effort, change really is possible if you want it. If you feel that your present way of life is unpleasant or has some difficulties, then don't look at these negative things. See the positive side, the potential, and make an effort.
