Observe the sensation and feeling in the body. Observing thoughts as thoughts, emotions as emotions, opens us to our true self, the godliness within us. The very observation changes it. When you do this, all that is negative falls away. 

The nature of positive emotions is to grow. If you observe your emotions (anger) when you are angry, anger will fall away. And if you observe if there is love, love grows.

That is the best and only way. Observe that thoughts come, and they pass. We need to be able to see things as they are, objectively or totally subjectively. That essence in life, when it blooms from within, allows true laughter in life.
