‘Buddhism teaches that we human beings cannot be fully satisfied after all, however hard we strive for it. I think that is the true meaning of the word dukkha in Sanskrit which is the first truth of Four Noble Truths. This word is often translated as “suffering” but it should be understood as a description of the fundamental fact in life that it is impossible for us to get ultimate satisfaction in this transient world.
When this feeling of unsatisfactoriness is driving us, we are never able to be settled and rest in peace and relaxation at the bottom of our heart. We need to let go of our deep-rooted tendency to look for exciting experiences to fill up the empty feelings of unsatisfactoriness or to try to distract ourselves from confronting unsatisfactoriness by indulging in all kinds of diversions. And we also need to settle down to unsatisfactoriness itself without trying to change it. To do zazen, we should clearly and deeply admit that there is no other way to authentic peace and just sit down with unsatisfactoriness.’ (from the Soto Zen Journal)
But of course we find that too unsatisfying!
