What is the source of happiness?
Sri Sri Ravi Shankar: What is the source of space? It is everywhere. Space is an element. Happiness has a source, it is our nature. When a baby has sorrow there is always a reason for sorrow. With that reason there is always a way to eliminate sorrow. But a baby is happy without reason. You can be happy without a particular reason. There is always a way to eliminate sadness. Bliss, joy, happiness is our nature when you have no reason to be unhappy. Unfortunately people always look for a reason to be unhappy.
Q: How do you find the ability to switch back into happiness?
Sri Sri Ravi Shankar: The ability to switch into happiness comes with practice. When you are thirsty, you need to drink. When you are unhappy, tired, lost and out of energy, you must do some breathing and meditation. Watch the emotion, leave it and observe. Look at the sky for a second. Observe the sensation. If you are tight in the throat, chest, somewhere, take a deep breath and relax.
