The essential way flows everywhere; how could it require practice or enlightenment? The essential teaching is fully available; how could effort be necessary? Furthermore, the entire mirror is free of dust; why take steps to polish it? Nothing is separate from this very place; why journey away?
And yet, if you miss the mark even by a strand of hair, you are as far apart from it as heaven from earth. If the slightest discrimination occurs, you will be lost in confusion. You may be proud of your understanding and have abundant realization, or you may have acquired outstanding wisdom and attained the way by clarifying the mind. However, even with high aspirations, if you wander about and get an initial glimpse of understanding, you may still lack the vital path that allows you to leap free of the body.
Observe the example of Shakyamuni Buddha at the Jeta Grove, who practiced upright sitting for six years even though he was gifted with intrinsic wisdom. Still celebrated is the Master Bodhidharma of Shaolin Temple, who sat facing the wall for nine years, although he had already received the mind seal. Ancient sages were like this; who nowadays does not need to practice as they did?
