This isn't necessarily a "prime mover" idea, but a somewhat similar theme. I just ignore the preachy parts and appreciate the raw comparison of life and death. It's written by Shunryu Suzuki.
I went to Yosemite National Park, and I saw some huge waterfalls. The highest one there is 1,340 feet high, and from it the water comes down like a curtain thrown from the top of the mountain. It does not seem to come down swiftly, as you might expect; it seems to come down very slowly because of the distance. And the water does not come down as one stream, but is separated into many tiny streams. From a distance it looks like a curtain. And I thought it must be a very difficult experience for each drop of water to come down from the top of such a high mountain. It takes time, you know, along time, for the water finally to reach the bottom of the waterfall. And it seems to me that our human life may be like this. We have many difficult experiences in our life. But at the same time, I thought, the water was not originally separated, but was one whole river. Only when it is separated does it have some difficulty in falling. It is as if the water does not have any feeling when it is one whole river. Only when separated into many drops can it begin to have or to express some feeling.
Before we were born we had no feeling; we were one with the universe. After we are separated by birth from this oneness, as the water falling from the waterfall is separated by the wind and rocks, then we have feeling. You have difficulty because you have feeling. You attach to the feeling you have without knowing just how this kind of feeling is created. When you do not realize that you are one with the river, or one with the universe, you have fear. Whether it is separated into drops or not, water is water. Our life and death are the same thing. When we realize this fact, we have no fear of death anymore, and we have no actual difficulty in our life.
When the water returns to its original oneness with the river, it no longer has any individual feeling to it; it resumes its own nature, and finds composure. How very glad the water must be to come back to the original river! If this is so, what feeling will we have when we die? I think we are like the water in the dipper. We will have composure then, perfect composure. It may be too perfect for us, just now, because we are so much attached to our own feeling, to our individual existence. From us, just now, we have some fear of death, but after we resume our true original nature, there is Nirvana. That is why we say, "To attain Nirvana is to pass away." "To pass away" is not a very adequate expression. Perhaps "to pass on," or "to go on," or "to join" would be better.
