A very practical sūtra because it invites us to practice these 4 principles. And these 4 are both familiar and do-able practices in day to day life. I am more and more attracted to the everyday-ness of practice as it's the majority of my life experience. So practical advice is welcome. Patañjali is indeed an absolute genius in presenting profound teachings in a way we can understand...with your help James, so thank you !!
