In every religion there exist sounds of a peculiar character, called "Words of Power," consisting of sentences in a particular language chanted in a particular way; each religion possesses a stock of such sentences, special successions of sounds, now very generally called "mantras," that being the name given to them in the East, where the science of mantras has been much studied and elaborated. It is not necessary that a mantra--a succession of sounds arranged in a particular manner to bring about a definite result--should be in any one particular language. Any language can be used for the purpose, though some are more suitable than others, provided that the person who makes the mantra possesses the requisite occult knowledge. There are hundreds of mantras in the Samskrit tongue, made by Occultists of the past, who were familiar with the laws of the invisible worlds. These have been handed down from generation to generation, definite words in a definite order chanted in a definite way. The effect of the chanting is to create vibrations, hence forms, in the physical and super-physical worlds, and according to the knowledge and purity of the singer will be the worlds his song is able to affect If his knowledge be wide and deep, if his will be strong and his heart pure, there is scarcely any limit to the powers he may exercise in using some of these ancient mantras. As said, it is not necessary that any one particular language should be used. They may be in Samskrit, or in any one of the languages of the world, in which men of knowledge have put them together. This is the reason why, in the Roman Catholic Church, the Latin language is always used in important acts of worship. It is not used as a dead language here, a tongue "not understanded of the people," but as a living force in the invisible worlds. It is not used to hide knowledge from the people, but in order that certain vibrations may be set up in the invisible worlds which cannot be set up in the ordinary languages of Europe, unless a great Occultist should compose in them the necessary successions of sounds. To translate a mantra is to change it from a "Word of Power" into an ordinary sentence; the sounds being changed, other sound-forms are created.
