In Sant Mat the Buddha is considered to be a Sant, a Satguru, a spiritual Master. "Sant Mat is theist Buddhism and could be referred to as Santayana (Vehicle of Saints)." (Domain
"As you calm down, you can experience the Sound of Silence in the mind. You hear it as a kind of high frequency Sound, a ringing Sound that's always there. It is just normally never noticed. Now when you begin to hear that Sound of Silence, it's a sign of emptiness — of silence of the mind. It’s something you can always turn to. As you concentrate on it and turn to it, it can make you quite peaceful and blissful. Meditating on that, you have a way of letting the conditions of the mind cease without suppressing them with another condition. Otherwise you just end up putting one condition over another." (Ajahn Sumedho, "The Sound of Silence")
"Listening to the inner Sound brings the heart into a position of acute inner awareness. It is not that the inner Sound has some magical property. Rather, it is that bringing of the alert mind, bringing openness and receptivity to Sound, is symbolic of the presence of Ultimate Truth. The Sound is always there. We don’t have to create it. It is featureless. It is ever present. So it is a good symbol for Ultimate Reality itself." (Ajahn Amaro)
"It is easiest to hear this Sound when it is quiet, particularly at night-time. Once you have identified this Sound, then you place your awareness on it without wavering. Resting your mind in the Sound, you continue to listen, going further and further into the Sound itself." ("Mind Beyond Death", Dzogchen Ponlop Rinpoche, Snow Lion Publications)
"Ananda and all you who listen here
Should inward turn your faculty
Of hearing to hear your own nature
Which alone achieves Supreme Bodhi.
That is how enlightenment is won.
Buddhas as many as the Ganges’ sand
Entered this one gateway to Nirvana.
All past Tathagathatas
Have achieved this method."

Upasaka Lu K’uan Yu Translation,
Published by Rider and Company, London)

Inner sound …
The Bible states, In the beginning was the Word, and the Word was with God, and the Word was God. (John 1:1) This Word is the Inner Sound. It has also been called the Logos, Shabd, Tao, Soundstream, Naam, or the Celestial Music. Master Ching Hai says, It (the Inner Sound) vibrates within all life and sustains the whole universe. This inner melody can heal all wounds, fulfill all desires, and quench all worldly thirst. It is all powerful and all Love. It is because we are made of this Sound, that contact with it brings peace and contentment to our hearts. After listening to this Sound, our whole being changes, our entire outlook on life is greatly altered for the better.
