This chakra has 12 spokes and is golden in color but many times can dip in various shades from golden yellow to pink or light orange. The Heart Chakra is located near the heart. However this chakra can float and be off-center to the left or right of the hara line. The optimum position should be dead center the hara, in line with the other chakras. This chakra is very important because it is the only chakra that can transmute the high-vibration energy that comes from the upper three chakras into a form that can be used by the physical body and on the physical plane. Healers (of all forms) use this chakra to heal their patients, as it is the Heart Chakra that transmutes the illness into a more dense form, which then passes through the Foot Chakra and into the earth for processing. The term 'a broken heart' refers to this chakra breaking off at the stem that connects the front part of the chakra to the back. This break causes the heart chakra to shut down causing that empty feeling we are all very much aware of. A missaligned Heart Chakra can cause lung and heart problems (especially angina from over-exertion), asthma, epilepsy, fibrosis, chronic bronchitis, depression, midriff pain and claustrophobia.
