The HeartMath Institute confirmed that when one is in heart coherence, the heart radiates more coherent electromagnetic signals, detected by the nervous systems of people and animals. I could go on endlessly on the science of the heart chakra, but I encourage you to look into it independently. In the meantime, take my word for it and practice front extensions/backbends. Heart openers release heavy emotions, those you may not know have even been stored. Expanding the sternum improves blood flow, oxygen and nerve circulation to mentally and physically invigorate. We tend to rest in a defeated slump (poor posture), causing a cascade of discomfort and disability. So open your heart, create a cascade of positivity, washing over you. To love unconditionally is to be in harmony with life itself.
