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.
Talking about connecting to a higher power: Whether we think of that higher power as God, or whether we think of that higher power as just our own inner wisdom, silence is absolutely imperative to get there...
That is where we always find our deepest wisdom.
Our activities in the world are really important. Being active helps us to gain skills and helps us to gain knowledge and build relationships.
But wisdom always comes out of silence.
