It is obvious we need a new social and economic organization. But the point is: How can we built a new society with the same minds? Impossible! To create new society we need to have new mental patterns. This is a consensus, I believe.
So the question is: How can we change old mental patterns?
Yoga seems to be a very useful tool. To transcend physical limitations is necessary transcend old postural patterns. With yoga we start to create new capacities, not only physical, once our posture is the results of our mental patterns.
