The peace for which every soul strives, and which is the true nature of God and the utmost goal of man, is but the outcome of harmony. This shows that all life's attainments without a sense of harmony are but vain. It is the attainment of harmony which is called heaven, and it is the lack of it which is termed hell. The master of harmony alone understands life, and he who lacks it is foolish in spite of all other knowledge that he may have acquired.
