For all problems of existence are essentially problems of harmony. They arise from the perception of an unsolved discord and the instinct of an undiscovered agreement or unity. To rest content with an unsolved discord is possible for the practical and more animal part of man, but impossible for his fully awakened mind, and usually even his practical parts only escape from the general necessity either by shutting out the problem or by accepting a rough, utilitarian and unillumined compromise. For essentially, all Nature seeks a harmony, life and matter in their own sphere as much as mind in the arrangement of its perceptions. (Sri Aurobindo)
