We are all joined in the holiness of the mind that God created. I therefore never consider myself alone in the silence. I'm 90 and live alone in a four room house surrounded by open space. I have no T and have always luxuriated in silence. The exterior silence is here. The i8nterior silence is a work in progress.
Breathing is one internal function that the conscious mind can control with comparative ease. The effect of controlled breathing is almost like communication with all conscious parts of one's being saying to them, "Simmer down and listen; there is something beyond the turmoil". It is communication in action that often works when words merely go in one ear and out the other, not even changing the cognitive mind. In essence, the effect is to turn all the elements of our will toward stillness and waiting.
