This cafe provides a great way to create awareness on death, thus, helping the people to better prepare to face death. When we are ready for death then we will not be afraid.
As Buddhist, we are encouraged to meditate on death everyday to create awareness of the nature of impermanence. Death Meditation is a very important practice for serious Buddhist practitioners, more so for the monks and nuns.
Tibetan Buddhism, especially, discussed widely on the topic of death. Highly attained lamas will remind students again and again to remember death, in order to be serious on one's own practice. The famous book: Tibetan Book of Living and Dying explains that the purpose of life is to prepare for death. This is so true because the moment we are born, we are actually a moment nearer to death...
"To make us mindful of death, the Buddha taught meditation on death. If you are mindful of death, you will be drawn into thinking of many things, particularly whether there is life after death. Even if you suspect that there is, you will take interest in the quality of that life — what it might be like.
This will lead you to think about Karma, the cause and effect of action, thereby drawing you away from choosing activities of harmful nature and encouraging you to engage in activities that are beneficial. This itself will lend your life a positive purpose.
If you try to avoid even the mention of death, then on the day when death comes, you may be frightened. However, if you contemplate the fact that death happens naturally to all living beings, this can make a big difference. When you become familiar with death, you can make preparations for dying, and decide what you should do with your mind at that time. On that day your preparation will have its effect; you will think “Ah, death has come,” and you will act as you had planned, free from fright." - the Dalai Lama in his book, Becoming Enlightened.
