So live your life that the fear of death can never enter your heart. Trouble
no one about their religion; respect others in their view, and demand that they
respect yours. Love your life, perfect your life, beautify all things in your
life. Seek to make your life long and its purpose in the service of your
people. Prepare a noble death song for the day when you go over the great
divide.
Always give a word or a sign of salute when meeting or passing a friend,
even a stranger, when in a lonely place. Show respect to all people and grovel
to none.
When you arise in the morning give thanks for the food and for the joy of
living. If you see no reason for giving thanks, the fault lies only in
yourself. Abuse no one and no thing, for abuse turns the wise ones to
fools and robs the spirit of its vision.
When it comes your time to die, be not like those whose hearts are filled
with the fear of death, so that when their time comes they weep and pray for a
little more time to live their lives over again in a different way. Sing your
death song and die like a hero going home.
Also this poem was mentioned at the end of the movie "Act of Valor" in 2012.
