"It is perhaps well to remember that the stage of discipleship is in many ways the most difficult part of the entire ladder of evolution. The solar angel is unceasingly in deep meditation. The impulses of energy, emanating from him are increasing in vibratory rate and are becoming more and more powerful. The energy is affecting more and more the forms through which the soul is seeking expression, and endeavouring to control."
