12. To act evil is for the majority of men far easier than to do good. Good will and desires to become useful must be made to accomplish some work. To overcome the resistance of evil and to put good into practice requires energy, courage and effort, and the _third_ necessary requirement is therefore _to dare_ to practice the good which we know and desire. 13. But as a power, after it has once been obtained, may be employed for good or for evil purposes, and as it is not desirable that persons with evil inclinations and tendencies, should be taught the way to prolong their personal existence after the dissolution of their physical form, because their existence would cause the infliction of injury upon others, and expose themselves to a long, slow and painful final disintegration; therefore, the deepest secrets of the Rosicrucians, and the way to the practical application of the secret knowledge, should be taught only to those who are good and pure to a degree sufficient to warrant that the mysteries communicated and revealed to them, may not be misapplied. The _fourth_ necessary requirement for the Rosicrucian is, therefore, _to be silent_, in regard to that which it is not expedient to speak. [Illustration:] HINDU SYMBOLISM. I. The student of Hindu metaphysical religious philosophy, will find most of its important formulations, veiled under a mystical symbolism; to understand which, is a key to the hints in the Upanishads and other esoteric writings. We propose to give those interested, a series of illustrations from Hindu drawings with descriptions; in the latter, our study of the Kabbalah has been of great assistance.
