What is nihilism and how is it related to Zen?
Think for a moment that there are stories other than yours, and that there are dreams and ambitions perhaps greater than your own. Now sustain this thought indefinitely. Consider, now, why your life is worth living in comparison to the lives of these others — the whole of humanity — and reason in way that does not resemble an excuse or an appeal to emotion. If you cannot justify your existence, I implore you: do not exist.
