Birth, death, old age and disease—these are the four problems of our life. Nobody wants to die, but death is sure. We must die. Nobody wants to take birth, but there is birth. Now there are so many contraceptive methods for checking birth. But still, the population of the whole world is increasing. So birth, death, old age. Nobody wants to become old, everyone wants to remain young and fresh, but old age overcomes. Similarly, disease. There are scientific advancement of knowledge, you have got very effective medicines, but there is no science to stop disease or to stop death. These are the actual problems.
But the problems, these problems, are pertaining to this body. The soul is different from this body. This is our misunderstanding. I am soul; you are soul. Ahaṁ brahmāsmi. But somehow or other, I have been entrapped in these bodily . . . material bodily changes. Changes, you can understand, that you had a body like a baby; you had a body like a child; you had a body like a boy. Now you have got youthful body. Some days after, you will get a body like me. So the body is changing, and I am the same. I can remember my childhood body, my babyhood body or my boyhood body.
