Merge with the silence before and after sound
Yasya Kasyapi Varnasya Purvantavanubhavayet
Shoonyaya Shoonyabhootosau Shoonyakarah Puman Bhaveth
Whoever meditates on the silence before the chanting of a mantra or sound and the silence at the end of the mantra - such a person who meditates on the silence, stillness and void - becomes that which he meditates upon.
Just like sound which has vibrations of a particular wavelength and frequency, silence also has the highest frequency of vibrations. when the mind focusses on something for a while, it becomes that. In this method, the mind that focusses on the silence becomes the silence itself. - Swahilya Shambhavi.
