The edge

In Geometry an edge can be considered the boundary of a shape.

The edge is the depth of a Yoga pose which you are most definitely challenged, but not so far that you experience injury or strain (www.evolationyoga.com).

Notice your edges in life as well – whether it be mental or physical or emotional..

In Ancient Egypt, students were required to master Yoga as part of their educational curriculum. (elev8.hellobeautiful.com)
