Harmony.

A man is alive when he is wholehearted, true to himself, true to his own inner forces, and able to act freely according to the nature of the situations he is in. To be happy, and to be alive in this sense, are almost the same. Of course, a man who is alive is not always happy in the sense of feeling pleasant; experiences of joy are balanced by experiences of sorrow. But the experiences are all deeply felt; and above all, the man is whole and conscious of being real. This state cannot be reached merely by inner work. There is a myth, sometimes widespread, that a person need do only inner work, in order to be alive like this; that a man is entirely responsible for his own problems; and that to cure himself, he need only change himself. This teaching has some value, since it is so easy for a man to imagine that his problems are caused by "others". But it is a one-sided and mistaken view which also maintains the arrogance of the belief that the individual is self-sufficient, and not dependent in any essential way on his surroundings. The fact is, a person is so far formed by his surroundings, that his state of harmony depends entirely on his harmony with his surroundings.
