Of all the chakras, the heart chakra is the most complex. That is where our sense of self exists. This is also the chakra of empathy and the one that psychics use to do readings. It is called the divine message center. Channeling also comes through this center. It explains the symbolism of having a divine being in your heart. Many times, spiritual icons are linked to the heart center. It is through our power of channeling that we bring through messages from the divine.
Even shamans link this center to their empowering spirit ally and it is through this center they channel spiritual healing power.
