The Solar Plexus Chakra is most strongly associated with mental health because it governs our personal power and self-esteem. It is the third chakra and is located in the upper abdomen. It helps us to have confidence and to trust in our own abilities. When this chakra is balanced, we have strong self-esteem, self-confidence, and the ability to make decisions for ourselves. An imbalance in this chakra can lead to feelings of low self-esteem, depression, and anxiety.
