Do not worry in the least about yourself, leave all worry to God,' - this appears to be the commandment in all religions. This need not frighten anyone. He who devotes himself to service with a clear conscience, will day by day grasp the necessity for it in greater measure, and will continually grow richer in faith. The path of service can hardly be trodden by one who is not prepared to renounce self-interest, and to recognize the conditions of his birth. Consciously or unconsciously, every one of us does render some service or other. If we cultivate the habit of doing this service deliberately, our desire for service will steadily grow stronger, and will make not only for our own happiness but that of the world at large.
