You... are going to die.
OK, I'm just kidding.
No, seriously... you're going to die.
Buddhism emphasizes being aware that you will die. In the zen-parable film Fight Club, Tyler Durden famously says:
"First you have to know... not fear, but KNOW... that someday, you are going to die. It's only once you have given up everything that you are free to do anything."
And in the film Ghost Dog, a young American mafia assassin strives to live by the ancient code of the samurai. He reads the following passage from his guidebook:
"The Way of the Samurai is found in death. Meditation on inevitable death should be performed daily. Every day when one's body and mind are at peace, one should meditate on being ripped apart by arrows, rifles, spears, and swords... being carried away by surging waves, being thrown into the midst of a great fire, being struck by lightning, being shaken to death by a great earthquake, falling from thousand-foot cliffs, dying of disease, or commiting sepuku at the death of one's master. And every day without fail one should consider himself as dead. This is the substance of the Way of the Samurai."
"Whoa, whoa.. hold up..." you might be thinking. "What's with all the gloominess? I thought Buddhism was about happiness... lotus flowers and chubby smiling Buddha statues and stuff."
Well, yes... and no. The Four Noble Truths of Buddhism state that "suffering" is caused by desire, but that suffering can be ended by ending desire. Ending suffering leads to happiness. What is the most basic desire of all people, in fact all living things? To live, of course. To not die.
The point isn't to welcome death, or to want to die. You would still step out of the way of a moving bus (hopefully). But the focus here is to reduce (or eliminate) your *fear* of death. Fears and anxieties are actually the types of "suffering" that the Four Noble Truths are talking about ending.
The Samurai took this elimination of the fear of death to an extreme (for the not-so-nice purpose of making themselves better warriors). But the general idea is straight from basic Buddhism.
