Either this important, or more correctly, vitally important process and the products of development arising from it are wholly unknown, or the possibility has been suppressed, which, with the aid of that which 'radiates' formatively, would enable the enlightening life-flame to be supplied with qualigen. Here we are concerned with the end-product of a life-affirming (reactive) metabolic process, the most highly evolved fatty-matter already in a metaphysical state, without which no increase in intellectual activity (ability) of any kind would be possible.

The Art of Music, which is music on its spiritual and inspirational side, has been carried to a wonderful perfection of development; while the Science of Music, which is music on its intellectual and logical side, has been left far behind. Works on the Science of Music have been a failure, not because music has not a scientific basis, but, and for the most part, because Mathematicians have dealt only with the law of Ratios, ignorant of other laws which play an important part in music's scientific basis and build. They have carried the law of ratios beyond its legitimate sphere, and so their conclusions do not represent the method of Nature truthfully. [Scientific Basis and Build of Music, page 33]

schools on the hill of Sion—'out of Sion hath God appeared in perfect beauty.' So long as this principle was recognised in musical academies, there were composers of the highest class; devoid of it, the highest order of compositions disappeared." "Power over music does not depend solely on the mere agreement of 'how to do it.' The student in song will never learn the perfection of beauty except from the preparation of the heart. To make a real musician, there must be a sense of the ever-presence of the Creator of all beauty. The boy-musician must begin his day with prayer, and end it with praise. This made Handel, Bach, Haydn, and Mozart. Music is neither dram nor sweetmeat, neither sensual nor intellectual. It is made so now; but in this order of music there is neither joy nor love, thankfulness nor reverence." [Harmonies of Tones and Colours, Fragments from Dr. Gauntlett's Last Note-book, page 51]
