道的精华

道可道，非常道。
名可名，非常名。

跟佛法 - 什么法相应呢？

Hint ： 禅

Human day to day living 行住坐卧 - is understood by all human as live, work, rest, play for survival - which is human mundane life. - 道可道。(这是世间法). (mundane universal law)。

From mundane life, if one practise "living in the present moment" - with "concentration" and "mindfulness" (定力，念力)  — one will attain "supramundane universal law" - 非常道。(这是出世间法)。

For eg. A person was taught to concentrate and mindful on sweeping the floor. He don't recite sutra and practise meditation. One day he attain Enlightenment with supramundane knowledge surpass all the monks that recite sutra and do meditation.

This is Zen (禅)。

All the rest of monks - are monks in name - 名可名。

The one that sweep the floor without formal monk training is 非常名 (not a monk by name, but a monk in substance).

This is Zen (禅)。

未观禅时，看山是山，看水是水。
观禅时，看山不是山，看水不是水。
观禅后，看山是山，看水是水。
