Hebrew רחק חבל.
"Or ever the רחק חבל [silver cord] be loosed... Then shall the dust [of the body] return to the earth as it was: and the spirit shall return unto אלהים Elohim who gave it." —Bible, Ecclesiastes 12:6
"When the soul leaves the body, its connection with the body remains intact, by means of what is termed the silver cord or magnetic tie." —Zohar
"Much has been said about the silver cord; it is indubitable that every soul is connected to the physical body by means of this magnetic thread. However, we have been told that a section of this cord or thread of life is found related to the heart and another to the brain. Diverse authors emphasize the idea that seven sections are derived from the silver cord and that these are found connected with seven specific centers of the human organism."—Samael Aun Weor, Hell, the Devil, and Karma
