The Devanâgarî characters in which Sanskrit is generally written, have all that the Hermetic, Chaldæan and Hebrew alphabets have, and in addition the Occult significance of the “eternal sound,” and the meaning given to every letter in its relation to spiritual as well as terrestrial things. As there are only twenty‐two letters in the Hebrew alphabet and ten fundamental numbers, while in the Devanâgarî there are thirty‐five consonants and sixteen vowels, making altogether fifty‐one simple letters, with numberless combinations in addition, the margin for speculation and knowledge is in proportion considerably wider. Every letter has its equivalent in other languages, and its equivalent in a figure or figures of the calculation table. It has also numerous other significations, which depend upon the special idiosyncrasies and characteristics of the person, object, or subject to be studied. As the Hindus claim to have received the Devanâgarî characters from Sarasvatî, the inventress of Sanskrit, the “language of the Devas” or Gods (in their exoteric pantheon), so most of the ancient nations claimed the same privilege for the origin of their letters and tongue. The _Kabalah_ calls the Hebrew alphabet the “letters of the Angels,” which were communicated to the Patriarchs, just as the Devanâgarî was to the Rishis by the Devas. The Chaldæans found their letters traced in the sky by the “yet unsettled stars and comets,” says the _Book of Numbers_; while the Phœnicians had a sacred alphabet formed by the twistings of the sacred serpents. The Natar Khari (hieratic alphabet) and secret (sacerdotal) speech of the Egyptians is closely related to the oldest “Secret Doctrine Speech.” It is a Devanâgarî with mystical combinations and additions, into which the Senzar largely enters. The power and potency of numbers and characters are well known to many Western Occultists as being compounded from all these systems, but are still unknown to Hindu students, if not to their Occultists. In their turn European Kabalists are generally ignorant of the alphabetical secrets of Indian Esoterism. At the same time the general reader in the West knows nothing of either; least of all how deep are the traces left by the Esoteric numeral systems of the world in the Christian Churches. Nevertheless this system of numerals solves the problem of cosmogony for whomsoever studies it, while the system of geometrical figures represents the numbers objectively.
