Heron Standing in Water

"The bird moves when it must; it does not move when stillness is appropriate.
The secret of its serenity is a type of vigilance, a contemplative state. The heron is not in mere dumbness or sleep. It knows a lucid stillness. It stands unmoving in the flow of the water. It gazes unperturbed and is aware. When Tao brings it something it needs, it seizes the opportunity without hesitation or deliberation. Then it goes back to its quiescence without disturbing itself or its surroundings. Unless it found the right position in the water's flow and remained patient, it would not have succeeded." -Deng Ming-Dao
