Compassion

Happiness is made of one substance – compassion. If you don’t have compassion in your heart you cannot be happy. Cultivating compassion for others, you create happiness for yourself and for the world. And because Avalokiteśvara is the embodiment of this practice, the Sutra says that we pay respect to him by bowing and touching our foreheads to the ground. This is an ancient Indian practice, a gesture of deep respect to one’s teacher.
