Chakras are the energy centers of our bodies. The heart chakra is located at the center of the chest. It's associated with the color green. It's connected to love, empathy, relationships, and forgiveness. When balanced, you may feel more loving, serene, tolerant, and compassionate. When unbalanced, you may feel more depression, jealousy, defensiveness and fear. You can use the affirmation, "I allow love in," when working with the heart chakra. It's connected to the element of air."
