This book is meant for sincere students, and especially for those who have some glimmering of what Krishna meant, when in Bhagavad-Gita he said, that… - William Quan Judge

The utterance of OM involves three sounds, those of long au, short u, and the "stoppage" or labial consonant m. To this tripartiteness is attached deep mystical symbolic meaning. It denotes, as distinct yet in union, Brahma, Vishnu, and S'iva, or Creation, Preservation, and Destruction. As a whole, it implies "the Universe." In its application to man, au refers to the spark of Divine Spirit that is in humanity; u, to the body through which the Spirit manifests itself; and m, to the death of the body, or its resolvement to its material elements. With regard to the cycles affecting any planetary system, it implies the Spirit, represented by au as the basis of the manifested worlds; the body or manifested matter, represented by u, through which the spirit works; and represented by m, "the stoppage or return of sound to its source," the Pralaya or Dissolution of the worlds. In practical occultism, through this word reference is made to Sound, or Vibration, in all its properties and effects, this being one of the greatest powers of nature. In the use of this word as a practice, by means of the lungs and throat, a distinct effect is produced upon the human body. In Aphorism 28 the name is used in its highest sense, which will necessarily include all the lower. All utterance of the word OM, as a practice, has a potential reference to the conscious separation of the soul from the body.

It is not a belief or dogma formulated or invented by man, but is a knowledge of the laws which govern the evolution of the physical, astral, psychical, and intellectual constituents of nature and of man. The religion of the day is but a series of dogmas man-made and with no scientific foundation for promulgated ethics; while our science as yet ignores the unseen, and failing to admit the existence of a complete set of inner faculties of perception in man, it is cut off from the immense and real field of experience which lies within the visible and tangible worlds. But Theosophy knows that the whole is constituted of the visible and the invisible, and perceiving outer things and objects to be but transitory it grasps the facts of nature, both without and within. It is therefore complete in itself and sees no unsolvable mystery anywhere; it throws the word coincidence out of its vocabulary and hails the reign of law in everything and every circumstance.

No one can really help you. No one can open your doors. You locked them up, and only you can open them. When you open any door, beyond it you find others standing there who had passed you long ago, but now, unable to proceed, they are there waiting; others are there waiting for you. Then you come, and, opening a door, those waiting disciples perhaps may pass on; thus on and on. What a privilege this, to reflect that we may perhaps be able to help those who seemed greater than ourselves! (Vol. I, Letter 1)
