Nichiren

"I, Nichiren, have studied Buddhism since I was a child. One's life is uncertain. Even if you exhale, you are not sure that you can inhale again. One dies quicker than the dew vanishes in the wind. The sage and the fool, the young and the old, are under the law of the transient life. Therefore, one should always know death comes to everyone and should accept it solemnly and spend their valuable life meaningfully."
