We have spent years, even decades, cultivating and grooming our own prisons. In the end, everything we cherish and value will be destroyed. It is 100% certain and there is no way around it. It's such a bleak thing to consider, yet at the same time it is an absolute truth.
After wrestling with these facts for years, I have come to understand the Zen koan about cherishing every moment drinking tea from a glass because to the master, the glass is already broken. Control of the larger world and the people within it are an illusion. In many respects, you are already dead and forgotten. The only thing you can do is admire the stunning beauty and sheer improbability of it all, and to be as kind as possible to those who deserve it, and to many who do not deserve it.
