The 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.
B.K.S. IyengarPranayama teaches the aspirant to regulate his breathing and thereby control the mind.
B.K.S. IyengarMany ask me whether pranayama ... postpones old age. Why worry about it? Death is certain. Let it come when it comes. Just keep working. The soul has no age. It doesn't die. Only the body decays. And yet, we must never forget the body, since it is the garden we must cherish and cultivate.
B.K.S. IyengarYou do not need to seek freedom in some distant land, for it exists within your own body, heart, mind, and soul.
B.K.S. IyengarAs a breeze ruffles the surface of a lake and distorts the images reflected therein, so also the chitta vrtti (fluctuations of mind) disturb the peace of the mind. The still waters of a lake reflect the beauty around it. When the mind is still, the beauty of the Self is seen reflected in it.
