Why do we use sound in meditation? “By sound one becomes liberated [Anavrittih shabdai],” is the concluding verse of the Brahma Sutras (4.4.22). How is this so?
Why do we use sound in meditation? Why not use one of the other senses or faculties, since touch, sight, taste, and smell must also possess increasingly subtler forms until they reach the point of their emerging? It is true that these four faculties do have subtle forms, but only sound reaches to the ultimate point of emergence.
The five senses correspond to the five elements of which all things consist. Those elements are ether [akasha], air [vayu], fire [agni], water [apah], and earth [prithvi]. That is, their grossest forms are those of sound [shabda], sight [drishti], touch [sparsha], taste [rasa], and smell [gandha] as perceived by the bodily senses. Because of this we use these terms to refer to them. But the water element is not just the liquid we call “water.” It is much more, having roots in the astral and causal planes. The same is true of the other elements.
The chain of manifestation
When relative existence, individual or cosmic, begins, there is a chain of manifestation. First there is the out-turning of the consciousness itself. This modification on the cosmic level is the emerging of the Mahat Tattwa, the Great Element, that is the Personal or Saguna Brahman, spoken of in Christianity as “the Only-begotten of the Father” or “Son” of God. In the individual this is the sense of asmita: I-am-ness. Then the Pradhana [Prakriti] modifies itself into the five elements, beginning with ether, and each succeeding element contains within itself some of the preceding elements. That is, air is mixed with some ether. Fire possesses some of the ether and air element. Water has some fire, air, and ether. Earth has some water, fire, air, and ether.
So only ether is unmixed, and only ether is “touching” the principle of Consciousness–only ether is in direct contact with the spirit. Yet ether (akasha) pervades all the other elements as their prime constituent–actually as their source and core element. Sound is the quality (or faculty) of ether; touch is the quality of air; sight is the quality of fire; taste is the quality of water; and smell is the quality of earth. Sound, then, is the only thing that reaches back to the principle of consciousness. The other elements stop somewhere along the way. Sound, then, can affect all the elements.
The five bodies or koshas
The five elements also correspond to the five levels or bodies known as koshas: the anandamaya, jnanamaya, manomaya, pranamaya, and annamaya bodies. These are the intelligence, intellectual, mental (sensory), biomagnetic, and physical bodies. The highest (most subtle) body is the etheric body (anandamaya kosha) which is the seat of sound or speech.
There is more. The other four elements have only one faculty or power, but akasha has two faculties or powers: Vak and Shabda–Speaking and Hearing. The faculties of the four other elements are all passive. The faculty of smell cannot generate smells, the faculty of taste cannot generate tastes, etc., though the memory or imagination of them is possible. Ether, on the other hand, has the capacity to both generate and hear sound on the mental levels. The etheric faculty both speaks and hears what it speaks, is both active and passive. This is unique among the elements. Akasha alone possesses the creative power, the power of sound.
Returning our awareness
Consciousness is the root of sound–is innate in sound. Sound, then, is the direct means to return our awareness to the inmost level of our being and put us into touch with consciousness itself. At the same time, sound rules all the levels of our being and has the ability to infuse all those levels with the highest spiritual consciousness, to spiritualize every bit of us. Sound is both energy and consciousness. Listening to our inner intonations during japa and meditation right away centers our awareness in the highest, etheric level of our being. It returns our awareness to its source and gathers up and centers every other aspect of our being in spiritual consciousness.
Through japa and meditation the Divine Sound pervades all our bodies, corrects, directs, and empowers them to perfectly and fully manifest all their potentials–which is the root purpose of our relative existence. All the aspects of our being are brought into perfect fruition and then enabled to merge back into their Source in the state of absolute liberation. Sound embraces all the aspects of our existence–not only the highest part–and is supremely practical perfecting our entire being.
