Rukha is an Old Testament word derived from the Aramaic term rukh. Rukh has been translated as spirit, energy, and wind. It also has been used to describe a sense of magnetism and electricity. Like the science of healing energy, rukh refers to an invisible force that produces visible results.
Koodsha represents an innate, undetectable, yet tangible force that can be transferred from one human being to another. In ancient teachings, this force was beneficial to humanity as long as intentions were aligned with the benevolent desire of God's will. In its most literal translation, the phrase refers to the Holy Spirit. It captures the very act of energy healing.
