 If you're doing something that's important for you, if you think your work is important, the first and foremost thing that you should do is you should work upon yourself. Inner engineering is a systematic way of working upon yourself. Not just in the body, not just in the mind, not just in the emotional level, but all aspects, your body, mind, emotion and energy, all these things are aligned and organized properly. This machine will work so much more efficiently. So the amount of sleep that you need, the amount of food that you need, the volume of rest that the body demands can be brought down considerably, at the same time the volume of activity can be greatly enhanced and made more efficient and more effective.
