Change is a fundamental element of consciousness. It is what calls our attention, awakens it, stimulates our questions. We see the red coat in contrast to the white snow... Without change, our minds become dull and unaware.
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.
