Sacrifice on the part of those above for the increase of those below fills the people with a sense of joy and gratitude that is extremely valuable for the flowering of the commonwealth. When people are thus devoted to their leaders, undertakings are possible, and even difficult and dangerous enterprises will succeed. Therefore in such times of progress and successful development it is necessary to work and make the best use of time. This time resembles that of the marriage of heaven and earth, when the earth partakes of the creative power of heaven, forming and bringing forth living beings. The time of Increase does not endure, therefore it must be utilized while it lasts.
