Don't think that those who enter the silence of God are "silent". Nothing could be farther from the truth! Silence is a thunder! You will be able to hear it everywhere. Your nights and days will be filled with it. ...Many confuse silence with solitude. Solitude is being alone with God, waiting for God. But silence is an immense sea into which you enter and never leave. And once you have plunged into this silence, you will always be silent.
In the Middle Ages people were well aware of the inexhaustible power that arises simply from sitting still... The inner quiet which arises when the body is motionless and in its best possible form can become the source of transcendental experience. By emptying ourselves of all those matters that normally occupy us, we become receptive to Greater Being. True enlightenment has the effect of so fundamentally affecting and shaking the whole person that they themselves, as well as their total physical existence in the world, is completely transformed.
