The Pericardium meridian is the mediator between the water tattva and the fire (agni) tattva if we look from the Ayurvedic point of view -- between our emotions in the second chakra and our passion in the third chakra, then rising up into the Heart. The fire tattva is purifying and transforming - its energy is not bound by gravity but rises up towards the heavens.
The Pericardium protects the Heart from emotional trauma, constricts the chest to protect the Heart, and helps to express the Joy of the Heart. It rules our relationships and the emotional issues around them. Emotionally, pericardium energy is related to the loving feelings associated with sexuality, thereby linking the physical and emotional aspects of sexual activity. It does so by moderating the raw sexual energy of the 2nd chakra/kidneys with the all embracing love generated by the 4th chakra/heart.
