I wonder what those people think about music. Especially polyrhythmic instruments (piano, drums, guitar when overlapping low and high tones). It's a massive walk into deconcentration of attention.
Also their mention about "pure mind" reminds me of an event 10 years ago. Got to job further than usual, 10km along a path on the forest, never been that far, it was a new environment. Sparse forest, calm, but disturbingly so. Sparsity allowed to see far away, but the perspective made trees difficult to differentiate from someone standing still. My mind turned into a hawk-like state. It wasn't fear like fight-or-flight, with accelerated heart beat, sweat, anxiety.. no it was more like a slight hunger and extreme calm focus (also I'm a thin, non combat/chaos trained person, being ready to survive was not a natural thing). My brain also operated faster.
