Introduction

Once we’re born, we start dying. So we might as well have a good time. At least, according to Cake in the song Sheep Go to Heaven. 

The question is, “What constitutes a good time?” This verse takes up that question. Sort of? 

Translation

Once we’re born,
  we start dying.

3 out of 10 follow life.
3 out of 10 follow death.
3 out of 10 of those alive rush to their deaths.
  Why? Because their life is so important to them.

It’s known that the Wise, in cultivating life,
  don’t encounter rhinos or tigers while traveling,
    or face danger when in the military.

The rhino has nowhere to stick his horn,
  The tiger has nowhere to scrape his claws,
    The enemy has nowhere to put his blade.

Why is this?
Because the Wise have no grave. 

Commentary

Once we’re born,
  we start dying. 

It is an obvious statement, though one most choose to ignore. How much different would your life be if you kept this at the forefront of your mind?

This verse describes the various ways people handle this truth. 

3 out of 10 follow life.
3 out of 10 follow death.
3 out of 10 of those alive rush to their deaths.
  Why? Because their life is so important to them.
