I have found that the greatest degree of inner tranquility comes from the development of love and compassion. The more we care for the happiness of others, the greater is our own sense of well-being. Cultivating a close, warmhearted feeling for others automatically puts the mind at ease.
For nine years, the first and third Mondays of the month, I am in silence; I do not speak to anyone for twenty four hours. It's life-changing. It has taught me to listen. When we listen with no responsibility to respond, we can listen fully, which allows us to hear so many things we would not hear if we were talking. This did not start as spiritual exercise, but it has become a very spiritual practice. You hear the truth from deep inside yourself.
