Patañjali describes asana in just three words: sthira sukham asanam. The posture should be steady and comfortable. That balance is the key to the whole practice.
Sthira
It means firm, solid, stable. It is the active side of the pose: well-rooted foundations, supporting muscles, a long spine, presence.
Sukha
It means comfortable, pleasant, free of unnecessary effort. It is the receptive side: free breath, a relaxed face, the ability to stay and adapt.
The balance
Sthira without sukha is rigidity: we force, tense up and get hurt. Sukha without sthira is slackness: we sink into the pose without presence. Sthira sukha describes an intensity that doesn’t break us, one we can sustain and direct.
How to apply it
- In every pose, ask yourself: which parts need to be active, and which can relax?
- If your breath catches, you have gone past your limit: back off a little.
- Look for the point where there is effort and, at the same time, calm.
This principle goes far beyond the mat: it is a good way to meet any situation in life.
