St John Of The Cross Quotes by Charles Cumming, Wayne Dyer and many others.

St. John of the Cross points out that the divine music can best be heard in solitude and silence. The sonorous music is not a physical sound that vibrates the eardrum but something transcending the senses. Physical solitude and silence remove the distracting noises that prevent us from hearing on deeper levels.
St John of the Cross told us that if a man wishes to be sure of the road he treads on, he must close his eyes and walk in the dark. I interpret that as a direction for us to trust in the guidance we receive from our invisible self.
