The Great 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 opinion for or against. The struggle of what one likes and what one dislikes is the disease of the mind.
