When: Whenever you are sitting with nothing to do. 

Step 1: Breathe From the Mouth

“Relax the lower jaw and let your mouth open just slightly. Start breathing from the mouth, but not deeply. Just let the body breathe so it becomes more and more shallow. And when you feel that the breath has become very shallow and your mouth is open and jaw relaxed, your whole body will feel very relaxed. 

Step 2: Feel a Smile

“In that moment, start feeling a smile — not on your face but all over your being — and you will be able to. It is not a smile that comes on the lips; it is an existential smile that spreads just inside. Try and you will know what it is, because it cannot be explained. No need to smile with your lips on your face but just as if you are smiling from the belly, the belly is smiling. 

“And it is a smile, not a laugh, so it is very very soft, delicate, fragile — like a small rose opening in the belly and the fragrance spreading all over the body.

“Once you have known what this smile is, you can remain happy for twenty-four hours a day. And whenever you feel that you are missing that happiness, just close your eyes and catch hold of that smile again, and it will be there. In the daytime as many times as you want, you can catch hold of it. It is always there.” 

Osho, This Is It!
