How can I incorporate the sound of Om during meditation?

Om is the fundamental sound of Sanskrit. In Om, all the sounds of Sanskrit are included. Om is made of A, U, and M—the joining of three sounds: A, U, M. These are the three primal vowels; the rest of language is born from them. All words are then constructed of these. Om is the root; A, U, M are its three branches; and from these three branches the whole web of sound and the birth of all words happens. The Jews would call Om the Logos; Christians would call it the Word. This sutra concerns this Om. Understand this sutra well. For those who would enter within can very easily do so with the support of this sound—because it is resonating within. Every moment this sound is echoing inside. This sound is your very life-breath. If this sound disappears within, you disappear.

THE LIBERATED PERSON, FOR WHOM BODY AND MIND ARE NO MORE THEN CLOTHING, ATTAINS TO SHIVAHOOD. OM! THIS IS DEDICATED TO LORD SHIVA. If your repetition is so fast and intense that there is no gap between two repetitions, no thoughts will come in between. If you relax your peace is the slightest, thoughts will creep in. So, repetition without any gaps! Do not worry about overlapping of the repetitions. Let them pile up on top of one another like railway cars in an accident.

18. Intone a sound audibly, then less and less audibly as feeling deepens into this silent harmony.

19. WITH MOUTH SLIGHTLY OPEN, KEEP MIND IN THE MIDDLE OF THE TONGUE. OR, AS BREATH COMES SILENTLY IN, FEEL THE SOUND "HH". 20. CENTER ON THE SOUND "AUM" WITHOUT ANY "A" OR "M". Now they say your age will be affected by it. If you go on daily changing your body routine, then if you were going to be alive for eighty years you will be alive only for seventy years. Ten years will be lost. And if you go regularly with the body clock, then if you were going to live for eighty years you will live for ninety very easily. Ten years can be added. Exactly like this, everything all around you has its own clock, and the world moves in cosmic time. If you enter the temple at exactly the same time every day, the temple is ready for you and you are ready for the…

15. Intone a sound, as aum, slowly. As sound enters soundfulness, so do you.

16. IN THE BEGINNING AND GRADUAL REFINEMENT OF THE SOUND OF ANY LETTER, AWAKE. 17. WHILE LISTENING TO STRINGED INSTRUMENTS, HEAR THEIR COMPOSITE CENTRAL SOUND; THUS OMNIPRESENCE. Sankya philosophy says that mind cannot be used: just understand this and take a jump. But yoga says this is impossible. Even this understanding is to be done by mind. Even with this understanding -- that you cannot use mind, that no technique will be of help, that every technique will become a hindrance and whatsoever you do will create a new conditioning -- you will still be using mind, you will move within mind. This too has to be understood by mind. So yoga says there is no way in which mind is not used; mind will have to be used. It should not be used positively, it should be used negatively. It should not be used in such a way that…

If you move from Om outward into the world, A U M unfold, and from them the entire expanse of sound. If you go behind Om, all sound dissolves; eventually you too dissolve—only Om remains. This means Om is not a sound produced by man; it is the sound of existence itself. As you have heard the sound of silence—at night when there is no noise, silence has its own hum—so when all ego and thought fall silent and deep quiet descends, the inner hush carries a sound: that sound is called Om. Entering Om, Krishna says, is entering me. Among all letters, I am the one-lettered Om. Among thousands of sacrifices, I am the sacrifice of japa. Let us understand japa. Yajna means any structured method by which we build a bridge between ourselves and existence—any plan that reconnects us.
