An excerpt from one of my favorite yoga books:
"Every yoga posture involves a 'push' and a 'yield'. Pushing is an active force that moves the body further and deeper into the posture, gently exploring areas of tightness. Yielding is a passive force with which you wait and listen to the moment-to-moment feedback from your body; it's a letting go of resistance that allows the active force to be successful without being aggressive. The pushing and yielding elements occur simultaneously, as in a dance. Done properly, therefore, yoga is a matter of pushing and yielding, of 'doing' and 'not-doing,' at the same time."
- Erich Schiffman, Yoga: The Spirit and Practice of Moving Into Stillness, p. 48
Isn't this how we should live life? To aspire for balance through pushing and yielding. We need that "push" to challenge ourselves, but we also need to know when to "yield" and let go of control.
More to learn. So much to learn.
