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.
It is all too easy and too simple to disdain as "superstition" everything one cannot understand, but the ancients themselves knew very well what they meant when they used symbolic language...the Spirit can always come back to breathe fresh life into the symbols and rites and give them back their lost meaning and the fullness of their original virtue.
