The “evil eye” — the stare that portends doom — has been noted since time immemorial, appearing in some form in virtually every culture. The sages of Kabbalah understood that seemingly harmless envious glances and looks of ill will are, in fact, anything but benign. These looks focus sinister forces on the object of their gaze, have tangible physical effects, and can actually halt progress toward one's potential in every area of life. The red string has been used for centuries by Kabbalists to counter these dark forces. Worn on the left wrist, the string seals protective energy within while intercepting negative energy from without. This best-selling book, the first in Yehuda Berg’s popular Technology of the Soul series, explains how and why this simple tool for healing and self-defense has worked for 5,000 years, and in the process gives a simple, clear overview of what Kabbalah is and is not.
