Anahata or the heart chakra is the subtle center of inner divine melody, believed to be located next to heart, located behind it along the subtle spinal column. It is believed to be the psychic energy center.
It is symbolised by a flower with twelve petals. It is represented as a circular flower with twelve green petals called the heartmind. Within it is a yantra of two intersecting triangles, forming a hexagram, symbolising a union of the male and female. The seed mantra is Yam, the presiding deity is Ishana Rudra Shiva, and the Shakti is Kakini.
In esoteric Buddhism, this Chakra is called Dharma and is generally considered to be the petal flower of 'Essential nature' and corresponding to the second state of Four Noble Truths.
