Do we not often notice the disturbing presence of people who have not got that tranquillity, that peace, that calmness? It is a terrible influence upon themselves and a disastrous influence upon others. One can realize this in one's everyday life. One may be sitting in an office with someone, one may be standing in a certain place, one may be staying in a house where other people are, and one can realize by their atmosphere whether they have reached a state of balance, tranquillity, calm, and peace, or whether they are out of rhythm, unbalanced.
