Seven

You probably know there are seven colors in a rainbow, seven notes in an octave and seven visible planets. You may be aware that the number seven features predominantly in most world religions: reference to seven in the Book of Revelations, seven Hindu chakras and seven candles on a Jewish menorah. There are seven virtues and seven deadly sins, Seven Wonders of the World and seven Islamic heavens. You may not know that there are 33 cities worldwide built on seven hills and that a mysterious Circaseptan rhythm of seven, regulating aspects of immune system processes, has recently been discovered. The number seven seems to be somehow wired into the biological and neurological structure of the human brain. Seven has permeated religions and mythologies, ancient and modern, and seems to be encoded in the basic structure of the natural world. There is no denying that the number seven pervades our world, unlike any other. Its consistent occurrence is eerie, puzzling and intriguing. This book brings together a compilation of sevens, uncovering a richly textured collage of synchronicity and mystery.Manning, Margaret is the author of 'Seven' with ISBN 9781410707291 and ISBN 1410707296.
