Neanderthals were making tar 200k years go. They were roasting crabs at least 90k years ago. They were making glue 50k years ago. They were tracking axial precession at least 40k years ago (hypothesized 70k years ago). It is very likely that they also knew how to dress themselves.

The very modern invention known as ‘Buddhism’ didn’t invent and doesn’t own traditional mindfulness. The practice of mindfulness, of ‘remembering‘, which includes remembering how to properly breathe as we evolved to, extends far back into the mists of time and cross-culturally, noting that even just observing the breath is ’working’ (consciously engaging) with it.

Authentic / traditional ‘mindfulness’ practice includes breathwork. If your “mindfulness” practice isn’t rooted in a foundation of breathwork, then it isn’t mindfulness practice.
