I'm not sure the yamas and niyamas relate to light and dark - they're not commandments, rather things to do or not do or challenge yourself on if you want to make progress towards the true self. The true self transcends light and dark not your actions towards it.

When I worked with prisoners that was all of my afternoons and it was brilliant and awful all at once ❤️

Yoga also has injury, ego, entrepreneurship, cultural piracy, exclusion... we have to accept the light with the dark. The lotus flower needs sun, water and lots and lots of mud ❤️

Yes good response, i obviously don't believe in assertions of such simplicity but the quote marks hopefully point to an acknowledgement of the views that some people hold and that I've genuinely heard.
