From A Chinese Garden of Serenity (1959), by Hung Tzu-ch’eng, translated by Chao Tze-chiang:

Life’s fortune and misfortune are caused entirely by the mind. Shakyamuni said: “A burning desire for gain is a pit of fire, and an indulgence in greed is a sea of suffering. Once our mind is purified, a flame is turned into a pool; and once our mind awakens us from a dream of worldliness, our ship of life is anchored along the shore of the Great Beyond.” Hence, a slight change of the mind can suddenly make a different situation. Should we not be careful?
