 The most responsible way to live is that you are playful with life. It's absolutely irresponsible to carry a long face and walk around in this planet. Being playful is being very responsible and responsive to life. Only when you are playful, you can pay attention to everything. You can truly respond to everything in the world. Only if you are playful, otherwise you cannot. Just the burden of it will kill you and only if one is playful, such a person can truly grapple with the problems in the world without being affected by it and do his best about it. If you maintain a few hours of playfulness in a day about what you're doing, you will see even your physical body will start functioning so much better. Your sleep quota will come down and meditation becomes a natural process for one who is playful.
