Earthly beings pass from one condition to another.
The world becomes another world, and it attains to a life-giving spirit. Thus the spring is the cause of new life and infuses a new spirit. Afterward comes the summer, when the heat increases, and growth and development attain their greatest power. Following this comes the season of winter, with cold and tempests. When this state is reached, again a new life-giving spring returns, and the cycle is renewed.
