From a collection of Thich Nhat Hanh's journal entries, Fragrant Palm Leaves: Journals 1962–1966
If you tarnish your perceptions by holding on to suffering that isn't really there, you create even greater misunderstanding. Reality is neither pleasant nor unpleasant in and of itself. It is only pleasant or unpleasant as experienced by us, through our perceptions. This is not to deny that earthquakes, plagues, wars, old age, sickness, and death exist. But their nature is not suffering. We can limit the impact of these tragedies but never do away with them completely. That would be like wanting to have light without darkness, tallness without shortness, birth without death, one without many. One-sided perceptions like these create our world of suffering. We are like an artist who is frightened by his own drawing of a ghost. Our creations become real to us and even haunt us.
