We must pass through solitude and difficulty, isolation and silence, to find that enchanted place where we can dance our clumsy dance and sing our sorrowful song. But in that dance, and in that song, the most ancient rites of our conscience fulfill themselves in the awareness of being human.
~ from "Letters of Solitude" in The Spirit of the Earth v. 5, no. 2
Inayat Khan tells the illuminating story of a disciple who came to the teacher and started to ask a philosophical question. The spiritual teacher was, however, in deep meditation from which he would not be disturbed. He said to the disciple: "SILENCE!"
This word was so powerful that the disciple went into silence -- and remained silent for the rest of his life. However, there came a time when his silence began to speak aloud. His silent thought would manifest and his silent wish be granted; his silent glance would heal; his silent look would inspire. His silence became living.
