Backbends are to be felt more than expressed. The other postures can be expressed and then felt. Like in meditation each person has to feel backbends.
B.K.S. IyengarBy persistent and sustained practice, anyone and everyone can make the yoga journey and reach the goal of illumination and freedom.
B.K.S. IyengarI also say with backbends, you have to be cautiously bold. Not carelessly bold. You have to descend to the dictation of the spine. You cannot command from the brain to do the poses. As you play with a child, guarding the child from injuries, similarly you have to play in backbends, guarding your spine.
B.K.S. IyengarDon't practice for cosmetic beauty, practice for cosmic beauty. Practice for inner beauty and inner light.
B.K.S. IyengarThe cure to combat the three Ss- stress, strain, and speed- can be found in three Ws- the work of devoted practice, the wisdom that comes of understanding the self and the world, and worship because ultimately surrendering to what we cannot control allows the ego to relax and lose the anxiety of its own infinitesimally small self in the infinitude of the divine.
