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.
All things are possible to those who believe, yet more to those who hope, more still to those who love, and most of all to those who practice and persevere in these three virtues.
