Spirituality is not some external goal that one must seek, but a part of the divine core of each of us, which we must reveal.
B.K.S. IyengarAnything physical is always changing, therefore, its reality is not constant, not eternal.
B.K.S. IyengarWhen you cannot hold the body still, you cannot hold the brain still. If you do not know the silence of the body, you cannot understand the silence of the mind. Action and silence have to go together. If there is action, there must also be silence. If there is silence, there can be conscious action and not just motion.
B.K.S. Iyengar
