The third chakra is called Manipura, translating to "jewel in the city". My teachers say through work on the third chakra, we will discover hidden talents and abilities (treasures) that were dormant in our beings before our practice began to reveal our highest self.
Our type-a culture has conditioned us to believe we are always falling short of something, instigating envy of others who we feel have a more "valuable" life experience. If scripture implies we have hidden treasure in our belly (!), why waste another second analyzing someone else's life?!
A yoga practice, which hones our inward focus and intuition, is the tool that's going to lift off the shame, blame, anger, and fear, allowing you to excavate your own self-worth. There is nothing out their to take in, as yoga teaches us every external component of our life is a reflection of the internal. The people we who have qualities and lifestyles we envy are in your life to remind you of something you already are. Additionally, Patanjali reminds us in the sutra's that when we are firmly established in not stealing, treasures will find their way into our lives seamlessly.
If we can cultivate an attitude that (in the words of one my favorite teachers ever) "we lack nothing" and trust our experience is perfect because it is our own, we'll stop reaching into the external world to validate ourselves. With this attitude we can kiss comparison good-bye and step forward fearlessly into our true self.
