Silence, music and logic are the three essential ingredients you have spoken of. How does logic relate to knowledge or consciousness?
Sri Sri Ravi Shankar: Logic is essential. If you see an idol of Goddess Saraswati, she is sitting on solid rock. She has a book in one hand which is logic. In the others, she has rosemary beads for meditation and veena (a musical instrument). Logic, music, mauna (silence) are all essential for total development of consciousness. Knowledge is logical understanding of existence.
