(Swami Achyutanand, Yoga of Inner Light and Sound)

"Since this Quintessential Vibration or Sound springs forth directly from God, it is imbued with the qualities of God and it bestows its own qualities upon its perceiver also, and has a natural propensity to attract its perceiver (soul) to its Source, thereby effecting the complete merger of the soul into the Supreme Soul that is God. That is why meditation on the inner Sound has been reckoned by sages and scriptures to be the loftiest of all forms of meditation."
