Kabbalah teaches that angels facilitate the circulation of energy throughout the non-physical universe. Invisible, intangible, and yet within us and all around us, angels serve as the infrastructure of the spiritual world. Some have existed forever — archangels, angels of the days of the week and of the zodiac, guardian angels, and the Angel of Death. But other angels are created through our actions — good or bad. Each action creates an angel that must transmit the meaning and impact of that action to the rest of the world and in our own lives. By changing our actions, we are able to harness the power of angels, transform ourselves, and find greater fulfillment.
