Backbends are not poses meant for expressionism. Backbends are meant to understand the back parts of our bodies. The front body can be seen with the eyes, but the back body can only be felt. That's why I say these are the most advanced postures, where the mind begins to look at the back.
B.K.S. IyengarThe material body has a practical reality that is accessible. It is here and now, and we can do something with it. However, we must not forget that the innermost part of our being is also trying to help us. It wants to come out to the surface and express itself.
B.K.S. IyengarOur greed comes from our fear that we will not have enough - whether it is money or love that we grasp. Yoga teaches us to let go of these fears and so to realize the abundance around us and within us.
B.K.S. IyengarThe yogi learns to forget the past and takes no thought for the morrow. He lives in the eternal present.
