The ego relies on the familiar. It is reluctant to experience the unknown, which is they very essence of life.
Deepak ChopraI think seriousness is a mask of self-importance and self-importance in turn is a mask for self-pity. So if you're really going to pursue a spiritual way of living in the world, you must be lighthearted and carefree, have humor, be able to tolerate ambiguity and embrace uncertainty, and be forgiving of yourself and everybody else.
