You may have airconditioning, but without the conditioning of the mind, how can there be peace? You may control prices, production of steel or cloth, the distribution of food-grains, and a number of other things and processes; but unless you have mind control, the rest are barren exercises. Mind control is more heroic and beneficial than any other system of control. A running train cannot be stopped, even if thousands hang on to it and pull it back but a tiny button in the engine, when it is pressed by the driver can bring it to a halt. So too, the mind, if controlled can bring to a halt, all the various functions which are sought to be controlled. Now, enormous time and money are wasted to achieve unessential targets, but, the most important target, namely, mind control is being neglected. Yoga is the name for that system of control. Now, Yoga is neglected; Udyoga (job) is being sought after. Udyoga without yoga will be a handicap, a hindrance. (SSS Vol.11)
