... the Upanishads speak of jyotir brahma, the Light that is Brahman. Very often the sadhak feels a flow of Light upon him or around him or a flow of Light invading his centres or even his whole being and body, penetrating and illumining every cell and in that Light there grows the spiritual consciousness and one becomes open to all or many of its workings and realisations. Appositely I have a review of a book of Ramdas (of the Vision) before me in which is described such an experience got by the repetition of the Rama mantra, but, if I understand rightly, after a long and rigorous self-discipline. "The mantra having stopped automatically, he beheld a small circular light before his mental vision. This yielded him thrills of delight. This experience having continued for some days, he felt a dazzling light like lightning, flashing before his eyes, which ultimately permeated and absorbed him. Now an inexpressible transport of bliss filled every pore of his physical frame." It does not always come like that—very often it comes by stages or at long intervals, at first, working on the consciousness till it is ready. <ref>https://incarnateword.in/cwsa/29/bhakti-yoga-and-vaishnavism#p48</ref>
=What is a Mantra?=
==Principle Of the Mantra==
The word is a sound expressive of the idea. In the supra-physical plane when an idea has to be realised, one can by repeating the word-expression of it, produce vibrations which prepare the mind for the realisation of the idea. That is the principle of the Mantra and of japa. One repeats the name of the Divine and the vibrations created in the consciousness prepare the realisation of the Divine. It is the same idea that is expressed in the Bible, "God said, Let there be Light, and there was Light." It is creation by the Word.<ref>http://incarnateword.in/cwsa/29/mantra-and-japa#p2</ref>

If rightly done, the mantra is a means of opening to the light and knowledge etc. from above and it ceases as soon as that is done.<ref>http://incarnateword.in/cwsa/29/mantra-and-japa#p9</ref>
==What Is Japa?==
Japa, like meditation, is a procedure—apparently the most active and effective procedure—for joining, as much as possible, the Divine Presence to the bodily substance. It is the magic of sound, you see. <ref>http://incarnateword.in/agenda/03/february-3-1962#p63</ref>
==Descent Of Force Into Sound- Ascent Of Sound Into Consciousness==
The Word—it is not pronounced speech and words. There are old traditions, which speak of "Let there be light and there was light." The Word is the Mantra. But it is something quite exceptional, it is when the will formulated in the spirit wants to come down into matter and act directly upon matter that it makes use of the sound—not only of the word but of the sound, the vibrations of the sound—to act directly upon matter itself, in matter. It is the opposite movement. You are in the region of thought formulated in words, then from there you may rise higher and get an expression of the silent idea; again from there you may rise yet higher and have the Force: the Force is the Consciousness which is the very source of that thought. And so it becomes a total consciousness instead of something formulated—expressed and formulated. That is, you climb right back to the source. From there, once you possess this light in itself, this consciousness in itself and want to act upon matter to produce a result, this will comes down from plane to plane, and as it becomes more and more material, it defines itself clearly in words or even in a single word, and when it touches matter, instead of its being a silent word, it becomes a word articulated with sounds: a vibrations that will act directly upon matter. But one must first have gone high up above in order to be able to come down again. One must have reached the silent consciousness to be able to descend and do this. It must come from above, the source of this word must be up there, not in any intermediary domain. That then is the Word. And one must do what I have said—it is not an easy thing. <ref>http://incarnateword.in/cwm/06/7-april-1954#p28</ref>
==Fashioned In The Heart, Confirmed By The Mind==
The mantra, though it expresses thought in mind, is not in its essential part a creation of the intellect. To be the sacred and effective word, it must have come as an inspiration from the supra-mental plane, termed in Veda, Ritam, the Truth, and have been received into the superficial consciousness either through the heart or by the luminous intelligence, manīṣā. The heart in Vedic psychology is not restricted to the seat of the emotions; it includes all that large tract of spontaneous mentality, nearest to the subconscient in us, out of which rise the sensations, emotions, instincts, impulses and all those intuitions and inspirations that travel through these agencies before they arrive at form in the intelligence. This is the "heart" of Veda and Vedanta, hṛdaya, hṛd, or brahman. There in the present state of mankind the Purusha is supposed to be seated centrally. Nearer to the vastness of the subconscient, it is there that, in ordinary mankind,—man not yet exalted to a higher plane where the contact with the Infinite is luminous, intimate and direct,—the inspirations of the Universal Soul can most easily enter in and most swiftly take possession of the individual soul. It is therefore by the power of the heart that the mantra takes form. But it has to be received and held in the thought of the intelligence as well as in the perceptions of the heart; for not till the intelligence has accepted and even brooded upon it, can that truth of thought which the truth of the Word expresses be firmly possessed or normally effective. Fashioned by the heart, it is confirmed by the mind. <ref>http://incarnateword.in/cwsa/15/indra-and-the-thought-forces#p25</ref>
