It happens because the body is there. Of course we have every right to avoid illness and pain, but in spite of that effort, when illness happens it is better to accept it. While you should make every effort to cure it as soon as possible, you should have no extra mental burden. That kind of rational attitude is quite useful. Now I want to speak about death.
Death is part of all our lives.
Whether we like it or not, it is bound to happen. Instead of avoiding thinking about it, it is better to understand its meaning. On the news we often see murders and death, but some people seem to think that death happens only to others, not to themselves. That kind of attitude is wrong. We all have the same body, the same human flesh, and therefore we will all die.
