Headphones are highly recommended but not required. The concept of the chakra appears to originate from the Vedas. According to these beliefs, it is an energy center in the etheric body. There are many different chakra systems, but the most popular is composed of 7 primary chakras. It is traditionally believed that the chakras represent systems that interact with the body’s biological processes. The heart chakra or Anahata is the fourth chakra, and is translated into: unhurt, unstruck, or unbeaten. It is the center and is found directly in the center of the chest, not precisely where the heart (organ) is. It is at the center of the seven primary chakras with three below and three above. This is the area where physical and spiritual meet. The prominent psychological lessons from this chakra are forgiveness, unconditional love and compassion.
