Inkling: Relax, Balance, Push

An inkling: relax, then balance the force, and once the force is balanced, push with the back leg.

Relax to absorb the force, after which you can balance it. Once the force is balanced, you can then push.

And relaxing is peng, I would say. One and the same. When you relax, you are in effect also doing peng. Which means you can then stick to his force, follow it, and redirect as needed. And that is why you can balance it, to bring it somewhere else where it can be used.

Many more inklings to go as I journey along...
