Whenever you feel that the mind is not tranquil—tense, worried, chattering, anxious, constantly dreaming—do one thing: first exhale deeply. Always start by exhaling. Exhale deeply; as much as you can, throw the air out. Throwing out the air, the mood will be thrown out too, because breathing is everything. And then expel the breath as far as possible. Pull the belly in and retain for a few seconds; don’t inhale. Let the air be out, and don’t inhale for a few seconds. Then allow the body to inhale. Inhale deeply, as much as you can. Again stop for a few seconds. The gap should be the same as when you retain the breath out—if you retain it out for three seconds, retain the breath in for three seconds. Throw it out and hold for three seconds; take it in and hold for three seconds. But it has to be thrown out completely. Exhale totally and inhale totally, and make a rhythm. Breathe in, hold; breathe out, hold. Breathe in, hold; breathe out, hold. Immediately you will feel a change coming into your whole being. The mood will go; a new climate will enter into you.
