Chakras are energy centers in the human body that affect people's spiritual, mental, emotional, and physical health. Archangel Zadkiel, the angel of mercy, is one of several angels who direct the healing work that people do within specific chakras.
Archangel Zadkiel oversees the heart chakra, which helps people learn how to love more deeply. The heart chakra energy center is located on the center of the chest.
Another angel -- Archangel Chamuel -- partners with Zadkiel to oversee this chakra.
