Then he should say: 'By the old age of the body, that (the ether, or Brahman within it) does not age; by the death of the body, that (the ether, or Brahman within it) is not killed. That (the Brah- man) is the true Brahma-city (not the body). In it all desires are contained. It is the Self, free from sin, free from old age, from death and grief, from hunger and thirst, which desires nothing but what it ought to desire, and imagines nothing but what it ought to imagine. Now as here on earth people follow as they are commanded, and depend on the object which they are attached to, be it a country or a piece of land,

In plain words: The answer is that what lives in the heart does not grow old when the body grows old, and it is not killed when the body dies. That is the real city of Brahman, not the body. It is the true Self, free from wrongdoing, old age, death, sadness, hunger and thirst, and it wants only what is truly right. The teacher begins to compare this with people on earth, who obey orders and depend on whatever land or thing they are attached to.
