Question: How can we keep the body pure while we are asleep?

Sri Chinmoy: Before you go to sleep, concentrate on your navel chakra for purity, and feel that this purity is revolving around the navel area. When you feel it revolving, speed up the revolutions. When it turns very fast, it scatters light all around, and impurity is illumined. Do this every night before you go to sleep.
