There is great beauty in what is involved in death and if there is any form of fear of death, we cannot understand the beauty of it. It is a matter of time, and death is particularly a matter of future. So when we think about it, we shut it up.
We take many pleasures of life and we often think about having the same again by tomorrow or days after, but when we do not have them or do not have any of them, there is pain.
Our pleasures mostly are very simple, and due to its simplicity, it gets easily lost. We need to be terribly clever to capture those pleasurable moments tightly and extend them till tomorrow and afterwards.
