Kabbalah: The Red String Book: Technology for the Soul, by Yehuda Berg. The Sages of Kabbalah understood that seemingly harmless envious glances and looks of ill will - the evil eye - are, in fact, anything but harmless. They have tangible physical effects and can actually halt progress toward one's potential in every area of life. In this unique book, Yehuda Berg explains the technology powering the Kabbalistic antidote to the evil eye, the Red String. The book shows how and why this simple tool of healing and self-defense has worked for 5,000 years. The book includes a free Red String and a mail-in offer to ward off the Evil Eye.
