禪林寶訓 1.45

1.45

白雲謂演祖曰。禪者智能。多見於已然。不能見於未然。止觀定慧。防於未然之前。作止任滅。覺於已然之後。故作止任滅所用易見。止觀定慧所為難知。惟古人志在於道。絕念於未萌。雖有止觀定慧作止任滅。皆為本末之論也。所以云。若有毫端許言於本末者皆為自欺。此古人見徹處。而不自欺也（實錄）。

Baiyun said to Yanzu, “The wisdom of Chan practitioners is mostly seen after the fact; they cannot see before the fact. Śamatha, vipaśyanā, concentration, and wisdom guard before the fact. Creation, stopping, letting go, and extinguishing are realized after the fact. Therefore, the function of creation, stopping, letting go, and extinguishing is easy to see, while the workings of śamatha, vipaśyanā, concentration, and wisdom are difficult to discern. Only the ancients had their resolve set on the Way, cutting off thoughts before they sprouted. Although there are śamatha, vipaśyanā, concentration, wisdom, creation, stopping, letting go, and extinguishing, they are all discourses on the fundamental and the derivative. Therefore it is said: ‘If there is even a hair's tip of talk about the fundamental and derivative, it is all self-deception.’ This is where the ancients saw through completely and did not deceive themselves.” (Veritable Records)
