This fourth technique is one that - in default of true ray knowledge - can be of general usefulness, because this fourth ray governs the fourth kingdom in nature, the human. The healer along this line of work (and such healers are practically non-existent at this time because the fourth ray is not in incarnation) heals primarily through the use of the appropriate sound or sounds. In the early stages when this technique comes into demonstration, music will be largely used by the healer to bring about a cure or to facilitate the process of death or departure. It will, however, be music with one constantly recurring chord, which will embody the note of the fourth ray and of the human kingdom. Healing by the means of sound will be one of the first healing unfoldments [710] to be noted at the close of the next century. More teaching along this line would be useless until the fourth ray again cycles into manifestation.
