The lake at the foot of the mountain evaporates. In this way it decreases to the benefit of the mountain, which is enriched by its moisture. The mountain stands as the symbol of stubborn strength that can harden into anger. The lake is the symbol of unchecked gaiety that can develop into passionate drives at the expense of the life forces. Therefore decrease is necessary; anger must be decreased by keeping still, the instincts must be curbed by restriction. By this decrease of the lower powers of the psyche, the higher aspects of the soul are enriched.
