反者道之动，弱者道之用。

The opposite sets the motion of the "Dao", while the weak are used by the "Dao".

否极则泰来，物极则必反。

When the negative reaches its extreme, the positive will arise; when things reach their peak, they will inevitably revert.

强弱且交替，生生且不息。

Strength and weakness alternate, life perpetuates without ceasing.
