Heart Chakra
From Sahaja Yoga Encyclopedia
The chakra of the Goddess lies behind the sternum bone in the spinal chord. This chakra is placed above the Bhavasagara, above the Void, as we call it in Sahaja Yoga. And the bridge that has to be crossed by the bhaktas, by the seekers, is guarded. She is the one. She helps Her children to come through that passage when there are negative forces trying to attack a seeker. (Shri Mataji Nirmala Devi 1 February 1983)
The Heart Chakra is also known as the Anahat.
