It is almost as if human affection is the very basis of our existence. Our life cannot start without affection, and our sustenance, proper growth, and so on all depend on it. In order to achieve a calm mind, the more you have a sense of caring for others, the deeper your satisfaction will be. I think that the very moment you develop a sense of caring, others appear more positive. This is because of your own attitude. On the other hand, if you reject others, they will appear to you in a negative way. Another thing that is quite clear to me is that the moment you think only of yourself, the focus of your whole mind narrows, and because of this narrow focus uncomfortable things can appear huge and bring you fear and discomfort and a sense of feeling overwhelmed by misery. The moment you think of others with a sense of caring, however, your mind widens. Within that wider angle, your own problems appear to be of no significance, and this makes a big difference. If you have a sense of caring for others, you will manifest a kind of inner strength in spite of your own difficult situations and problems. With this strength, your problems will seem less significant and bothersome. By going beyond your own problems and taking care of others, you gain inner strength, self-confidence, courage, and a greater sense of calm. This is a clear example of how one’s way of thinking can really make a difference.
