From the Hsu Yun Ho Shang Fa Hui
Edited, Translated and Explained by Lu Kuan Yu [Charles Luk]
MASTER HSU YUN'S DISCOURSE IN THE CH'AN HALL
(Dear friends,) you have been coming frequently to ask for my instruction and I really feel ashamed (of my incompetence). (Every day) from morning to evening, you have been all hard at work splitting fire-wood, tilling the fields, moving earth and carrying bricks. In spite of this, you still remember your religious duties; this earnestness of yours does indeed warm the heart of other people. I, Hsu Yun, feel really ashamed of my incompetence in religion and lack of virtue. I am not qualified to give instruction and can only pick up a few sentences left behind by the ancients in reply to your questions.
PRELIMINARIES TO THE METHOD OF TRAINING
There are many kinds of method but I will deal briefly with them.
PREREQUISITES OF THE PERFORMANCE OF RELIGIOUS DUTY
(1) Firm belief in the (law of) causality
Whoever One may be, especially if striving to perform one's religious duty, one should believe firmly in the law of causality. If one lacks this belief and does whatever one likes, not only will one fail in the performance of religious duty, but also there will be no escape from this law (of causality) even in the three unhappy ways.[1] An ancient master said: 'If one wishes to know the causes formed in a previous life, one can find them in how one fares in the present life; if one wishes to know the effects in the next life, one can find them in one's deeds in the present life.' He also said: 'The karma of our deeds will never be wiped out even after hundreds and thousands of aeons (but) as soon as conditions become ripe, we will have to bear the effects ourselves.' The Surangama Sutra says: 'If the causal ground is not a true one, the ripening (fruit) will be distorted' Therefore, when one sows a good cause, one will reap a good fruit (and) when one sows an evil cause, one will reap an evil fruit; when one sows melon (seeds) one will gather melons (and) when one sows beans, one will gather beans. This is the plain truth. As I am talking about the law of causality, I will tell you two stories to illustrate it.
