Your right energy channel (Pingala nadi), also called the sun channel, begins at your Swadisthan chakra and travels up the right side of your body, terminating in the ego area of the brain. The ego is the area of your brain that gives you a sense of individualism and self, as distinct from others.
It is the ego that allows you to relate to yourself as “me” or “I.”
Action and planning are essential qualities associated with the right energy channel. They drive your mental and physical activities. However, the demand for energy on the right side can sometimes be so great that the left side is weakened. When this occurs, your desire for joy may evaporate, and you find yourself grouchy and irritable. You may even feel like yelling at everyone or “flying off the handle” when the slightest thing goes wrong.
Unfortunately, you have likely encountered many stressed out, irritated and agitated people. This is because it can be difficult to maintain a balance of emotion and action when our workplaces and schools are stressful, aggressive environments. It can also be difficult to maintain a peaceful, nurturing home where these imbalances can be corrected. As a result, the negativity, stress and aggression continue to build. Fortunately, awareness is the first step to correcting imbalance. Meditation, and accessing your Kundalini energy to restore harmony, will allow you to do so.
In summary, your right energy channel influences your ability to plan and take action for the future. It also plays a role in negative emotions such as anger, irritability and stress. Your right channel thinks in terms of “I,” “mine,” and “myself.” Overdo any of these and you may become unpleasant to be around. However, your meditation will tell you when your right channel energy is too high and when it’s time to cool down and re-balance.
