There are two sutras that mention asana in Pantanjali’s Yoga Sutras and this is one of them.
Sthira sukham asanam: the posture is steady and comfortable.
There is a challenge in yoga of finding that beautiful balance between effort and ease. That place where you feel your body, strong and solid, blood pumping, and your muscles are working and yet at the same time a place where you could hold the posture all day. Your breath is even and your mind is still.
Those moments on my mat are the moments that I crave. It is a feeling of being in mid air, not going up or falling down its just being present with strength but without struggle.
As we move through this life may we all find moments of that balance, effort and ease. May we work hard but find joy in our work, may we run up those hills even when they seem too big but know that we can relax into the earth, that our legs are strong and that our breath is steady.
