The flute is the symbol of the spiritual call — the call of the Divine Love

"To Thee who has been the material envelope of our Master, to Thee our infinite gratitude. Before Thee who has done so much for us, who hast worked, struggled, suffered, hoped, endured so much, before Thee who has willed all, attempted all, prepared, achieved all for us, before Thee we bow down and implore that we may never forget, even for a moment, all we owe to Thee." The Mother.
