Yielding vs Following

The important thing in taiji is not to resist your opponent's force. But that does not mean yielding to his force. There is a difference between yielding (譲) and following (随).

When you yield, you are not resisting, and your opponent's force comes in, and you end up with nowhere else to go.

But taiji is not about yielding. First, you need to be aware of your opponent's force, so you listen/feel for it. Then you need to stick to it, so that it doesn't slip away. Then you follow it to where it is going. And then you lead it towards where you want it to go. The reason why you do not resist your opponent's force is so that you can feel where the force is and where it is going, so that you can then lead it towards where you want it to go.
