Spiritual factors of value to esotericists today are included here with clarity and vision. Esotericism is shown as a practical science of service, in which the subjective and spiritual aspects of life can be related to human need and world affairs in effective ways. The old tendency in spiritually awakening people toward isolation from mundane daily life and to dependence on a so-called spiritual 'authority', is ending. The esotericist is also a man of goodwill and a member of the new group of world servers, responsible for the well-being of the human race in conformity to the divine Plan. He learns and grows through the results of his own experience in relating spiritual principles to daily life.
