The sages tell us  that our essential nature is truth, consciousness, and bliss, and  that the source of our misery is estrangement from our essential  nature.
Although the mind searches  unceasingly for ways to end it’s suffering, they say, it usually  confines its search to the external world and thus find only more  misery. And even when we gain enough wisdom to look within, at first  we encounter only scattered or uncontrollable thoughts, feelings, and  daydreams. The sages agree that meditation is the path that leads to  absolute reality, but that a scattered mind is sure to cause delays,  Mantra, they tell us, is the vehicle by which the mind becomes  one-pointed and inward and thus reaches the eternal silence that is  the source of bliss.
The power of mantra
A mantra  is a revealed word, a divine sound that has been received or  experienced by an adept in the state of deep samadhi (spiritual absorption). It is a condensed  form of spiritual energy, the sound body of the Divine Being. It can  also be thought of as a compact prayer. The yogic scriptures often  compare mantra to a boat or a bridge that an aspirant can take to  cross the mire of delusion created by the external world and reach  the center of consciousness within. Mystics and yogic say that mantra  is an eternal friend who accompanies the meditator even after death,  lighting the way in the realm where the light of the sun and the moon  cannot penetrate. According to the more esoteric literature of the  yoga tradition, mantra is the essence of guru  shakti, the power of the spiritual master. In  other words, the mantra is itself the guru. Mantra, God, guru and  one’s highest self are identical.
The branch  of metaphysics known as spanda, the  science of eternal vibration, hold that all creation evolves from the  Word. Here “Word” does not refer to speech uttered by a human  voice or the audible sound produced when two objects strike each  other. The Word is anahata nada, the  unstruck sound, which vibrates eternally in the realm of pure  consciousness. It is the Word that existed before the beginning of  creation.
The power  of mantra is not limited by time, space, or causation, for mantra is  a self- existent, self-luminous reality that can be heard by all who  have ears to hear. But mantra transcends sound for, as the scripture  say, mantras are seen by the eyes of the soul rather than heard by  the ears. One blessed with the vision of mantra is a rishi (seer).
To have that vision,  one needs purity of heart and a perfectly one-pointed mind. Only this  will prepare the seeker for the brilliance of the transcendental  light in which the sense of duality vanishes. In the glory of this  revelation the seer and the seen become one. In that moment, that  which was unmanifest becomes manifest in the form of mantra and  radiates in the inner chamber of the seer’s heart. From that time  on it shines forth, and seekers are naturally drawn to the one who  embodies it. That is how the science of mantra comes down to us  today. The seers who received the Word were blessed with its power,  and this power manifested spontaneously in their actions and speech.  Thus, the seers drew aspirants to them and they, in turn, prepared  for and received the Word themselves. Thousands of years later this  revelation still illuminates the path of true seekers.
Revelation 
Our normal  speech has no capacity to transmit the infinite knowledge and bliss  which dawns from within. The world’s mundane languages are like the  early morning fog; the rays of mantra are the light in which this fog  evaporates, illuminating the horizon of our inner world. The seer,  bathed in this illumination, communicates in a language, which the  yogis call sandhyabhasa, the  twilight language. This is the original, universal language that  existed before the confusion of tongues described in the Old  Testament account of the Tower of Babel.
The sages did not take  part in building the Tower of Babel, and their communication with the  Divine was not interrupted. But as we have built our own tower of  ego, attachment, desire, anger, hatred, jealousy, and greed, we have  lost touch with the universal language, and this severely limited the  sages’ ability to share their knowledge with us. To a select few,  however, often on a high peak or in some other secluded place, they  did manage to communicate in a mystical language that was neither  wholly nor completely spiritual. But in order to be understood at  all, they had to dilute the content of their message at the cost of  blocking the full force of the revelation. Even then it was hard for  most people to get a glimpse of it. Those who heard it understood  only part of it, and as they attempted to share their experience,  misunderstandings inevitably resulted. Disciples often asked,  “Master, why do you speak in parables?”
This is the paradox of  initiation: in spite of a master’s deep longing to share his  knowledge, the disciple’s inability to receive it limits the  intensity of the transmission. Those who have not properly equipped  themselves cannot receive direct knowledge of the ultimate truth.  That is why, in the end, Moses laid his hand only on Joshua; Krishna  laid his only on Uddhava; and Christ gave the key of Word only to  Peter. And that is why, even though the wisdom that is mantra has its  source in supreme truth, this truth flows down to seekers in various  grades and degrees. It clothes itself in the grab of different  languages, and seekers identify it as a Sanskrit mantra, or a  Buddhist mantra. These identification are only partially true. The  transforming power of mantras, even in their articulates from, is  beyond ordinary perception. 
Mantra  and meaning
As the  eternal truth, the Word is indivisible and indestructible. But there  are an infinite number of mantric revelations of this truth. In the  yoga tradition, for example, there are meditative mantras that  promote spiritual unfoldment and mantras for siddhis (supernatural powers).
Meditative mantras,  which are found mainly in the Upanishads, are used as tools for  contemplation, for ordinarily, when aspirants know the meaning of the  mantra they are practicing, a feeling for it develops during the  course of meditation. The meanings of mantras are so condensed and  compact that aspirants may need to ponder them repeatedly over a long  period of time. As they do so, the meaning manifests in a continuous  wave, illuminating the interior chambers of the mind and heart, and  thus transforming the meditator. 
On the  other hand, most of the highly secret, mysterious, and potent mantras  (called mahavidyas)  consist of one or more syllables that do not form a word. Their  transformative power lies in the sound of the mantra itself.  According to the mantravedins (the  knowers of mantra science), if such mantras are received in the  course of an authentic initiation, they will keep on manifesting  spiritual fervor in the heart of the practitioner, helping to unfold  the psychological conditions as well as the determination an aspirant  needs to follow the path. 
Whatever form they  take, the purpose of all meditative mantras is to enable seekers to  go beyond the confines of the mind and have a direct experience of  their own essential nature. In the last analysis, however, it is not  the meaning of the mantra but its subtle vibrations that lead (or  carry) the meditator to the center of silence within. This process  cannot be understood intellectually. It must be experienced  personally.
The  universal mantra
The most  easily recognizable inner sound is the sound of the breath. It you  sit in a quiet place and attend to its flow, you can easily hear the  sound so as you inhale and the sound hum as  you exhale. The sound so-hum reverberates effortlessly as we inhale and exhale. But the sound is  subtler than the breath. It is a universal mantra. We are all born  with it. Our life depends on it. Our breathing follows the rhythm of  life contained in it, and paying attention to that sound as we inhale  and exhale is attending to the rhythm of life itself. These are not  symbolic statements. They are facts you can verify by your own  experience. Stress, fear, and anxiety vanish the moment the mind is  allowed to rest in so-hum.
This  mantra comes from the Upanishads, ancient scriptures written in  Sanskrit, but so-hum is not a Sanskrit word in itself. It is a compound of the Sanskrit  words sa (that) and aham (I am). Thus, the literal translation is “That I am.” When  rendered according to English syntax, it becomes “I am That.” 
A more  profound meaning of so-hum comes when you understand that Sanskrit is patterned on the rhythm of  the life force. Sanskrit was developed and perfected by seers who had  the ability to hear those subtle rhythms. It you inhale without  exhaling, you will hear sah, but  if you begin to exhale without pausing at the end of the inhalation,  you will hear so, for sah automatically turns into so as  it merges with the oncoming ah in aham. The sages  created the grammatical rules of Sanskrit on the basis of the natural  way those sounds merge.
Life  continues as long as so and hum keep flowing  in a circle. “That” (the Cosmic Being) and “I” (the  individual being) remain united until their bond is broken by the  pause we call death. 
Learning  to meditate with a mantra
To approach meditation  systematically, begin by quieting and balancing the physical body,  cultivating a comfortable, stable sitting posture, and learning how  to make the breath serene. That is the purpose of the physical  postures and the breathing practices of hatha yoga. The next step is  to withdraw the mind from external affairs and begin the practice of  breath awareness. In the beginning, observe how the breath flows from  the tip of the nostrils to the heart center, and back again. At  first, you will find that this simple practice creates a feeling of  tranquility because it is in marked contrast to the usual habit of  letting the mind wonder at will. But as the superficial mental  clutter begins to recede, more subtle habits surface, and breath  awareness no longer bestows such a deep feeling of peace.
At this  stage, meditation on the mantra so-hum is  introduced. And because this sound has the intrinsic ability to draw  the mind inward, it induces a deeper state of tranquility than does  the practice of breath awareness alone. But again, after a period of  months or years, as the mind becomes calmer and you gain access to a  deeper level of your being, even more subtle and problematic habit  patterns become visible. This is the point at which initiation enters  the picture. It is also the point at which mantra science becomes  esoteric. There is a noticeable effect when you use  so-hum as an object of meditation. You will  see a result whether you understand mantra science and have faith in  it or not. But for the next level of mantra meditation, which you  enter during the course of initiation, you must have some degree of  insight into mantra science and faith in its validity. 
The  transforming power of mantras is beyond ordinary perception.
Why? Because, through mantra  initiation, you are working systematically to bring successively  deeper levels of your inner experience into conscious awareness. This  process not only refines and purifies the existing impressions in the  mind, it also cultivates and deepens the experience of the mantra and  creates a positive groove in both the conscious and unconscious mind.  But in the beginning, before you are aware of the deeper levels  within, it is almost impossible to observe and appreciate the deep  changes that are taking place. Students who do not understand the  science of mantra often become disheartened, feeling that their  mantra is not the “right” mantra. At that point they may seek  other practices or simply abandon the path of meditation altogether.  Either way, the fruit of this discouragement is skepticism, and this  is one of the chief obstacles to spiritual attainment. 
For this reason, before  you seek mantra initiation, it is important to carefully consider the  following questions: What compels me to look for further guidance?  How do I know that I am ready for initiation? How cam I be certain  that the person who initiates me is part of an authentic spiritual  lineage and has attained direct experience of mantra? How do I know  this person is not just someone who has read a lot of books and is a  persuasive speaker? Is initiation necessary for my further growth  development? What commitment on my part is part is implied by  accepting initiation, and what can I expect from the teacher? 
The  meaning of initiation
The scriptures tell us  that seekers must avoid the two extremes of behind faith and  skepticism. Understanding your true motives for seeking initiation  requires both purity of heart and sharpness of intellect. Are you  seeking mantra initiation just because you read an inspiring article  or attended a riveting lecture? Listen to the cry of the soul for  liberation. That will help you decide whether or not it is the time  to seek initiation.
Don’t seek initiation  simply because you have tried a number of other options and it seem  that you might as well try this one too. The right time is when your  longing becomes so intense that waiting any longer is painful. This  intense yearning is the fruit of your good karma, and along with it,  the natural process of unfoldment begins. The power of your yearning  draws the master toward you, and when that happens you will  experience the fulfillment of the scriptural promise, “ Seek and ye  shall find; knock and the door will be opened.”
Longing,  curiosity, confusion, skepticism, and occasional struggle are all  part of the mystery of mantra.
Because mantras are  one with universal truth, they cannot be claimed by any particular  denomination, creed, nationality, or lineage.
As for the qualifications of the  initiator, it has been said that a good student cannot end up with a  bad teacher. To determine if you’ve found the right path, the right  tradition, and the right teacher, ask yourself how spontaneously and  effortlessly you are drawn in that direction. Observe carefully what  is reflecting in your mind, and listen attentively to what is echoing  in your heart. Because mantras are one with universal truth, they  cannot be claimed by any particular denomination, creed nationality,  or lineage. If a mantric tradition has a sectarian or cultish feel,  that is a sure sign it is not connected with the source that  transcend all superficial faith, religions, and creeds. Thus it  cannot serve as a channel for transmitting universal and  unconditional truth. If that is the case, don’t get involved.
Another pitfall is  dependence. The mind has formed the habit of becoming dependent on  others, hiding its weaknesses, and blaming others for its mistakes.  Many students, after reading inspiring books on mantra initiation,  yoga, and the student-teacher relationship, start building castles in  the air. They think that once they get a mantra or are initiated by a  powerful teacher, their problems will be over. The scriptures  discourage such thinking, but unfortunately, many teachers do not.  Instead, they encourage their students to build high expectations and  become dependent on them. Avoid involving yourself in such a  situation. Expectation is a source of misery, and dependency is  bondage. 
Mantra  shastra, the literature of mantra science and  practice, is specific about the rules and laws of initiation. It  describes who to initiate, when, and how. It makes clear that it is  the responsibility of the teacher to acquire a profound understanding  of these points before coming forward to guide a student. Even more  important, mantra shastra insists that teachers be trained by a  competent master who has the power to bless them, to guide them from  within, and to set them straight if they begin to misguide others. 
A  personal note
When I approached  masters in the course of my own search, none of them gave me any  verbal promises, although each one guided me lovingly, helped me to  expand my vision, and revealed just enough for me to overcome any  remaining skepticism. They all stressed the importance of not seeking  or accepting knowledge blindly. They were all totally selfless and  willing to give me any worldly possessions they had. They offered  guidance and inspired me to study and learn. 
But when it comes to  initiation I found them miserly. Eventually, they instructed me in  mantra practice, but never in the exact mantra that I wanted to  learn. They loved me deeply, but in the realm of spirituality they  did not care what I wanted. Instead they gave me what I needed. Many  of them planted a seed both subtle and glorious, but they did so in  such a mysterious way that I came to know what they had done only  much later when the seed sprouted and began to blossom. By then I was  so far away from them in the realms of space and time that I could  not express my gratitude. I realized with amazement that those great  ones were like the helping hands of God, systematically guiding me to  master who would finally initiate me.
Such is the mystery of  mantra. The longing, curiosity, confusion, skepticism, and occasional  struggle with obstacles are all part of that mystery. The more we  know, the more we want to know, for the more we know, the more we  feel how little we know. Fortunate are those who have a burning  desire to know and the resources to experience the Word. Like the  seers of the Divine Word, may we also hear, receive, and keep the  Word and be purified by it? May the divine light one-day descend in  our lives and proclaim the name of the Absolute Truth.
