Hagakure.

«Whether people be of high or low birth, rich or poor, old or young, enlightened or confused, they are all alike in that they will one day die.
It is not that we don't know that we are going to die, but we grasp at straws.
While knowing thatwe will die someday, we think that all the others will die before us and that we will be the last to go.
Death seems along way oft . Is this not shallow thinking?
It is worthless and is only a joke within a dream.
It will not do to think in such a way and be negligent. in so far as death is always at one's door, one should make sufficient effort and act quickly.»
