The section that begins in 6,19 concerns knowing where one’s priorities lie. Treasure stored on earth is of not much use because it is temporary and passing and gathers rust and also can be stolen. Rather heavenly treasure is permanent and eternal. A person’s attention will be concentrated on where his/her treasure is. Thus instead of concentrating on the temporary it is better to concentrate on the eternal, the impermanent. If one does not perceive correctly, one’s whole orientation will be incorrect and one will live a life of futility, concentrating on what is really not essential.
Sometimes we lose focus in our lives and waste so much time on trifles. We are so concentrated on gathering up for tomorrow and the next day, that the present day passes us by and we find that we have live it unaware. An occasional examination of our priorities is required to bring back our focus on what is really necessary.
