Jason Schramm of Detroit Yoga in Royal Oak Michigan demonstrating Kukkutasana from the Ashtanga Primary Series.
To attain Kukkutasana one must first put in many months or sometimes years of consistent practice. Receiving gradual progressions from an experienced teacher.
There are almost no real "ah-ha" moments in practice, but instead many hours of time and energy invested. The fruits are born from the daily efforts not so much from the prize of "getting" a new posture.
