Embodying the physical feels like taming a wild lion, or putting my hand on its forehead and taking all of its energy into myself. Or like the moment when a ghost is sucked into the trap in Ghostbusters—fast-moving energy instantly consolidated and made still.
The keys are:
It's like continuously climbing up and flopping over the edge of a life raft. There needs to be attunement and focus to get myself up to the top of the slippery ledge, but once I'm there I need to relax and fall into the bottom of the boat. And this happens constantly, such that the two movements become one.
Another image would be climbing up onto a surf board. What had felt like waves flowing over me now feels like a constant, steady ground beneath me.
