How often people are inclined to say, “My lot has put me in the wrong place. I am,” let us say, “a postal clerk. If I were put in a different place, I could give people high ideas, great teaching,” and so on. The mistake which these people make is that they do not enter into the significant aspect of their occupation.
If you see in me something of importance because I can talk to the people here, then you do not see the importance of your own life and work. If the mail-carriers did not carry the mail, the whole postal traffic would stop, and much work already achieved by others would be in vain. Hence everyone in his place is of exceeding importance for the whole, and none is higher than the other.
