The Bard's Still Handy.
To paraphrase, there are more things than are dreamt of in the octagon.
By that, I mean there's a difference between a meditative practice and a practice for active use. Techniques originally developed in natural and/or historical settings where there's limited space to move can be adapted to apartment buildings, shopping centers, and schools. Not to mention adapted around new legislation - I want to say that the timing was somewhere in lockdown, but this information fits the geographical location and the issue of reasonable restraint.
Ending with this because, if I understand it correctly, it's like using a grid of telephone wires for map coordinates, without being able to 'hear' what the wires themselves are carrying.
