This is the fate that waits a living art. This is why I started taping some lessons to allow students to see better where they are lacking.
Some things you can see and some things you can’t. A video gives you a third party perspective of what you are doing.
I taped this fajing demo as part of a lesson. Even with explanation I noticed that some movements can’t be captured on video.
And even with explanation certain things are best felt rather than heard. This is why to learn Tai Chi you need to see it, hear it and feel it.
What can’t be seen clearly in how to neutralize the pressure by grounding it. You can only see the issuing movement. That’s like reading half the story.
Perhaps one day VR can be used to enhance distance learning. Until then treat our art as impermanent and pass it on to as many as possible to ensure its continuing existence.
