The essence of fiery advancement comes from various affirmations of spirit. The chief factor will be the development of self-activity. In self-activity will be contained love for Hierarchy; in it will be contained a feeling of responsibility and a true understanding of Service. Thus when We speak of self-activity, one should understand that it includes all qualities of higher affirmation. When a co-worker takes upon himself the development of self-activity, his field of action becomes unlimited. Hierarchy becomes the fiery impetus of all his actions. No attacks, near or far, are frightening to the co-worker, because he knows fiery service. Therefore it is so important to purify one’s consciousness from selfhood. But the co-worker must be prepared to accept all difficulties, knowing that Service to Hierarchy is the highest attainment. (FW III (opens in new tab), 39)
