【The Origin of Suffering】- causes of death  

There are a few causes of death. There is one which is the exhaustion of your lifespan. Another one is the exhaustion of your merit. Here it talks about "the exhaustion of your life span."  

【that was projected by your previous karma; as the time has come, you die.】

 Karma that you created in your past life, it has produced the effect of this life for you. For the effect of this one lifetime, you have only this much time. Therefore, the lifespan that has been projected by your past karma is complete at this moment! And therefore, "as the time has come, you die."  This is called "the exhaustion of your life span.". What is the other kind?  

【Death from exhaustion of your merit means,】  

So it is called "the exhaustion of your life span," or it is called "the exhaustion of your merit." That is for our projecting and completing karma, yes, these dictates however long your life is going to be in this life and the amount of merit you have. This exhaustion of merit means that although your life span is not exhausted yet, but your blessing merit is exhausted. Sorry, in other words, hey, you have nothing to eat!

【for example, dying deprived of the necessities of life.】

希求解脱 : 死缘

死的缘有好几种，有一种寿尽而死，有一种福尽而死。现在呢有一种叫“尽寿死者”，

【谓如宿业所引寿量，一切罄尽而死，是为时死。】

就是说你宿生造了什么业，那么这一生感得了这样的一个果。这一生果，说你的寿量就是这么多，所以你宿生所引的这个寿量，到此满了！那个叫“时死”，那个叫“寿尽之死”。还有一种呢，

【福尽死者，】

或者叫“寿尽死”，或者“福尽死”，就是我们引、满当中就是，是的，你这一生寿命有多长，然后你有多少的福报。还有一种这个福报尽了，虽然你的寿命还有，可是你福报尽了，对不起，换句话说，欸，你没得东西吃了！

【谓如无资具死。】
