We have to become like the ebb and flow. This is a symbolical expression. A certain thing is accomplished at one time by sympathy, and at another time by indifference; one situation we must meet by taking interest in it, in another situation we must become indifferent, not concerned with it. If in a sea there were always ebb and no flow, or always flow and no ebb, then this would be a dead sea. The living sea is both inhaling and exhaling; thus in everything we do in life, we should be able to meet every situation and event with the manner that the situation demands.
