Wu/Hao's Rock or Wei Shu Ren's Energy Ball, which is it?

[TaiChiTJ]

In the Wu/Hao teaching at 11:05, a door is imagined in the chest that supports a rock. The doors open and the the rock drops into the lower torso.

In Wei Shu Ren's animation, at 0:32, the door is shown and an energy ball drops at 0:36

So I guess its anybody's choice.
