The way to develop the power in oneself to withstand all disturbing influences in everyday life is to quieten oneself by means of concentration. Our mind is like a boat in the water, moved by the waves and influenced by the wind. The waves are our own emotions and passions, thoughts and imaginations; and the wind is the outer influences which we have to cope with. In order to stop the boat one should have an anchor, an anchor to make the boat lie still. Now this anchor is the object we concentrate upon; if it is heavy and weighty then it will stop the boat, but if this anchor is light the boat will continue to move and not be still, for it is partly in the water, and partly in the all."
