The Ultimate End
At risk of sounding awkward, death is the ultimate end that all of our means aim to achieve. In no way do I want to "achieve" this any time soon, but to imagine the moment at which it is about to happen is very important. I can only dream of how at peace the world must seem, how nothing else matters at that point, and how even your deepest and largest of worries vanish. No other activity is a greater motivator. All else is just a way to understand and cope with such an ambiguous life every day. Meditation is a very interesting practice.
