Manipura (Navel Chakra)
Element: Fire
Color: Yellow
Sound: Ram
Life theme:
You’ve heard the expression “firing on all cylinders.” When the Manipura is in balance, you feel alive and have the self-esteem and confidence to take action and be productive. When it’s blocked, you lack courage, have low self-esteem, and feel stagnant and inert. By working on this chakra, you can awaken your true personal inner power and work through your fear of taking risks.
