Yamas and Niyamas
The Yamas and Niyamas are the foundational principles of being in Yoga. These ethics and practices help one to embody the wisdom and oneness and bring it in to the waking state.
Although this diagram is linear, I don't find the practices to work in that way. For when one gets a glimpse of pure freedom, one wonders how to bring that to the waking state, and the Yamas and Niyamas are a guide for doing just that.
