The way is not difficult for those who have no preferences. When love and hate are both absent everything becomes clear and undisguised. Make the smallest distinction, however, and heaven and earth are set infinitely apart. If you wish to see the truth then hold no opinions for or against anything. To set up what you like against what you dislike is the disease of the mind. When the deep meaning of things is not understood the mind's essential peace is disturbed to no avail.
From the Hsin Hsin Ming, or "Verses on the Faith-Mind," translated by Robert B. Clarke. I took the liberty of slightly altering his translation by replacing "tao" with "way."
This Classic Chinese Buddhist poem is ascribed to Sengcan, the Third Chinese Zen Patriarch, who died around 606 CE. This poem has long been revered as containing the essence of Zen teaching.
