Huang Po said this quote

Not till your thoughts cease all their branching here and there, not till you abandon all thoughts of seeking for something, not till your mind is motionless as wood or stone, will you be on the right road to the Gate.

~ Huang Po

Observe things as they are and don't pay attention to other people. There are some people just like mad dogs barking at everything that moves, even barking when the wind stirs among the grass and leaves.

~ Huang Po

The ignorant eschew phenomena but not thought, the wise eschew thought but not phenomena.

~ Huang Po

Consider the sunlight. You may see it is near, yet if you follow it from world to world you will never catch it in your hands. Then you may describe it as far away and, lo, you will see it just before your eyes. Follow it and, behold, it escapes you; run from it and it follows you close. You can neither possess it nor have done with it. From this example you can understand how it is with the true Nature of all things and, henceforth, there will be no need to grieve or to worry about such things.

~ Huang Po
