Spiritual life is essentially a life of silence. It means learning to experience deepening, chastening states of inner quietude. What does love of God imply? Experiencing that calmness which can cure our ignorance. The more we love God, the more we become silent in the spiritual sense. There is no longer any "noise" from the turbulent mind. In the Upanishads, God is described as Shivam shantam, the essence of goodness, the essence of silence.
