Death is a period of "recharging" for our next existence.

Josei Toda often compared death to sleep. When we have been awake for a long time, we tire and go to sleep. And when we wake up after a sound sleep, our vitality is restored. After we have been alive for a long time, we grow weary and die. And then we set out on a new life with a fresh spirit. Death is a period of "recharging" for our next existence.
