The Nature of Yoga is to shine the light of awareness into the darkest corners of the body.

Bringing attention to where your emotions feel in the body it is a very helpful tool for self healing. Bringing your awareness in those places while you are doing yoga poses helps dissipate the grasp those emotions have on you. The emotions are a form of energy and they usually show up right where the chakras or wheel of energy are located.

Chakras are energy centers and access point to tap our full potential and power. The whole spine is a pole of energy vortexes. After practicing yoga and meditation the chakras are open and activated because unconsciously with each pose we tap into one or more of these centers but we can also do it in a conscious way. Sometime you feel heaviness between your eyebrows or you have a choking feeling in your throat, or your feel your stomach churning. Use those signals as a map for your work.
