天下之至柔，驰骋天下之至坚。无有入无间，吾是以知无為之有益。不言之教，无為之益，天下希及之。

Te Ching Chapter Forty-three

The softest of all things can overcome the hardest of all things.

Regardless of being or the non-being, they all have to return to the empty void to express their gentleness.

Thus, I have learned the benefits of natural actions without personal desires.

Very few can understand the value of wordless teaching and due act of natural Way.
