Here I would touch upon one important point connected with all Words of Power. I could give you these words in their ancient Sensa form, but it would not be possible for me to teach, through the medium of writing, their ancient and peculiar pronunciation or the note upon which they should be sounded forth. This used to be regarded of supreme importance. Today, disciples are being taught to work far more upon the inner planes of meaning and not to depend, as heretofore, upon the outer activity of sound. Remember that you are not creating now upon the outer plane. The physical sound or sounds are therefore of relatively no importance. What does matter is the ability of the disciple to feel the meaning of the Word of Power as he silently utters it. It is the quality of his idea which will bring the right effect, and not the way in which he makes a sound with the aid of his vocal cords and his mouth.
Students have been taught that the A.U.M. sounded inaudibly and listened for, is of greater potency than when sounded audibly. This was preparatory to the utterance of these Words of Power. They have been learning the significance of the O.M., even if they did not realise it. This was all in preparation for the use of the Ray Words. It is the thought behind the form, the registered feeling anent the words, and the understanding of their significance which are of importance; it is the ability to think, to feel and silently to send out the call of quality to quality, of meaning to meaning, of nature to nature, of form to spirit which matters, remembering ever that that which is found upon the physical plane is not a principle. The physical sound is not that which will lead to a successful building of the antahkarana. It is the quality of a particular  type of subjective nature (the soul ray as it dominates the personality ray) which makes appeal to that which is still more subjective; that is what in truth accomplishes the work. It should be borne in mind that from the angle of the Spiritual Triad the soul nature is definitely objective. This is a statement of occult fact which will be better understood when the nature of man (as taught in the occult sciences) is admitted by thinkers, scientists and psychologists.
The point I wish to make is that no particular word is going to be given by me, because it would be useless. The O.M. is useless to most people, even though trained students may now be deriving benefit from its use. This general uselessness is caused not only because people do not use the Word correctly, but also because, even when using it they are not holding its significance firmly in their consciousness. So it is with a Word of Power. Of what use would it be if I attempted to give the Word of the first ray, which looks (when presented in its symbolic written form) something like this—UKRTAPKLSTI? Certain sounds in this word-form are omitted because there is no way of depicting them, since they are neither vowels nor consonants. Correctly sounded, the above forms three words. But I can give, as far as possible, the English equivalent in meaning, and it is this meaning which I ask you to have in mind as you mentally utter the sound or Word of Power and visually attempt to see it performing the esoteric miracle of bridge building.
The first ray disciple has, therefore, to meet the requirements to the best of his ability and to follow the four stages of the technique of projection (pages 489-493, 509). When he has faithfully followed this outlined routine, personality and soul fusion has to be consciously attempted and to some measure achieved, and then these blended factors are held steady in the triadal light. Another point of focussed intention is now brought about, resulting in a new and still more dynamic tension. In the completed silence which results, the act of projecting the antahkarana is performed,  and it is then carried forward on the impetus of a Word of Power. The symbolism connected with this lies behind the Masonic usage of the words, translated into English, "So mote it be," uttered with the right hand stretched forth and signifying the embodied will of the Lodge, itself a symbol of the Will and Purpose of the Most High.
The meaning of the Word of Power to be used at this point of accomplished projection might be summed up in the words: "I ASSERT THE FACT." This is the nearest form I can give you for the word-form earlier mentioned. A little deep reflection on these words will show that if uttered with an understanding of their meaning, they are of terrific potency.
The disciple who utters them assumes and then asserts:
1. The Spiritual Triad is a fact.
2. The relation between the fused and blended personality and the soul is a fact.
3. The antahkarana is also a fact.
4. The dual expression of the basic duality of manifestation—personality or form and Monad or Spirit—is a fact.
5. The will of the Monad is the factor to be evoked.
6. The knowing, purposeful One can be depended upon to contact the instrument of its will upon the physical plane.
7. The work is done.
This factual assumption is not faith, but knowledge and conviction, and upon this realised conviction the disciple rests, acts and depends. It becomes an unalterable and unchangeable attitude. The meaning of the above seven-fold statement will become clearer if the disciple will ponder the distinction between faith and conviction. It is this divine assertion which holds the universe in being; it is this divine assertion which is the embodied summation of all knowledge and love, and the first ray disciple must begin to use this technique, resting back upon his divine prerogative of assertion. Ponder on this statement. It is the  technique of Shamballa and the established right, prerogative and privilege of all first ray souls.
Again the first two stages of Intention and Visualisation have been carefully followed and the four stages of the Projection have been carried through to their highest point. The vivid light of the second ray soul (the most vivid in this second ray solar system) dominates the light of form and radiates out to the triadal light. Then comes a moment of intense concentration and the peculiar Word of Power of the second ray is enunciated. Of this Word, the dual symbol SXPRULXS takes form in the mind of the disciple and signifies the assertion: "I SEE THE GREATEST LIGHT." This statement has relation to the Central Spiritual Sun and not to the Heart of the Sun; it involves, if I might so express it, the most intense effort to see in the light the relation of the whole, and this is one of the most potent experiences to which the disciple can be subjected. It is not vision or even aspiration to see the vision. It is complete sight and of this the Masonic symbol of the "Eye of God," the "All-Seeing Eye," is the expression. It involves realisation of the light of the divine countenance; of this the light of the soul is the dim reflection. The disciple has learnt the significance of solar and lunar light (soul and form light), but this is something other. It is the great obliterating light of reality itself, revealing the fact of the higher Lighted Way which leads to Nirvana; Of this, the projected antahkarana is the stage first consciously realised by the disciple.
I am faced with difficulty in making these Words of Power clear to you, because essentially it is the Word made flesh or the soul in incarnation which at this point registers power; it is the symbol (the form aspect) and the power (the Spirit aspect) which acts as a great creative agency and bridges across all barriers and separative states of consciousness, thus establishing complete unity.
I have indicated to you certain vowels and consonants  which are the nearest approach which I can make to making these Words clear, and I have done so in the case of the first and second rays. I shall give you no others, as it is entirely useless. I shall only give you the significances, the concepts involved and the meaning of which these archaic word-forms (which I have attempted to portray in Anglo-Saxon letters) are the embodiment. As the race passes more and more into the world of meaning, these word-forms assume less and less importance, and only the concentrated thought, based on understanding comprehension, can achieve the results. It is into this somewhat new form of work we are now pioneering.
Ray Three... Active Intelligence
The processes of Intention and Visualisation have been followed, and again the four stages of the Projection technique have been concluded. At the point of highest tension, the disciple utters the Word of Power for the third ray. It is not easy for the disciple on this ray to achieve the necessary focal point of silence; his intense fluidity leads to many words or to great mental activity, frequently carried forward under the impulse of glamour. This lessens the potency of what he seeks to do. But when he has succeeded in achieving "mental silence" and is simply a point of intelligent concentration, then he can use the Word of Power with great effectiveness. The difficulty is that he has to overcome the tendency to use it with the idea of physical plane results in his consciousness. Always he works from the angle of that divine quality which characterises matter; just as the second ray disciple works always from the angle of quality and the first ray disciple from the positivity of spirit. But once he intuitively comprehends and factually grasps the concept that spirit-matter are one reality, and once he has achieved within himself the sublimation of matter, then he can divorce himself from all that the human being understands in relation to form. He can then utter the Word of Power which will make possible his complete identification with spirit, via the antahkarana. This word is "PURPOSE ITSELF AM I"
As regards the other and remaining Words of Power connected with the four Rays of Attribute, I shall simply list them, as there is little that I can say about them. They can be comprehended in the light of what I have said anent the three Words of Power used upon the Rays of Aspect.
Ray Four...Harmony through Conflict
"TWO MERGE WITH ONE"
Ray Five...Concrete Knowledge or Science
"THREE MINDS UNITE"
(This asserts the fact that the Universal Mind, the higher mind and the lower concrete mind are blended through the projected antahkarana.)
Ray Six...Devotion or Idealism
"THE HIGHEST LIGHT CONTROLS"
Ray Seven...Ceremonial Law or Order
"THE HIGHEST AND THE LOWEST MEET"
You will note that in all these Words of Power, two obvious thoughts emerge; first, that the goal of all activity is the complete fusion of the three Aspects, and secondly, that consciousness of this comes through the building and use of the bridge between the Spiritual Triad and the Personality. You will note that these are all definite assertions, based on knowledge leading to conviction. The various schools of affirmation found today throughout the world are but the distorted efforts of humanity to arrive at the affirmative position which the blended soul and personality always necessarily assumes, and demonstrate a kind of instinctual reaction to a new realisation which is coming into the consciousness of humanity, via its disciples and initiates.
We have practically concluded our study of the antahkarana; however, I want to enlarge a little further upon the three final stages of the building process as dealt with and outlined earlier. These three stages were most briefly considered, owing to their abstract nature. They are part, however, of the six building methods. The first three were considered in greater detail than the last three, and I have felt that it might serve a useful purpose if I gave more teaching anent Invocation and Evocation in particular, for it will condition—consciously and exoterically—the new world religion, as it has hitherto conditioned it esoterically and unconsciously.
