The realms of good fortune and calamity in human life are all made of thoughts and imaginings. Therefore Buddhists say that the burning of desire for gain is itself a pit of fire, while drowning in greedy love is itself a bitter sea. The moment thoughts are pure, fierce flames become a pond; the moment you become aware, the boat has arrived on the further shore. If your thoughts vary at all, your world will immediately differ, so can we not be careful?
