"All verbal teachings are just to cure diseases. Because diseases are not the same, the remedies are also different. That is why it is sometimes said that there is Buddha, and sometimes it is said that there is no Buddha.

True words are those that actually cure sickness; if the cure manages to heal, then all are true words. If they can't effectively cure sickness, all are false words.

True words are false words when they give rise to views. False words are true words when they cut off the delusions of sentient beings. Because disease is unreal, there is only unreal medicine to cure it."

-Zen Master Pai-Chang
