The Fifth Chakra is Called your Throat Chakra. This Chakra is connected to both hearing, and being heard, being able to communicate, to transmit and receive the Truth.
If this Chakra is off balance or shut down, you will have all sorts of problems with self-talk and inner voices. You may repress your ability to express yourself and be honest, or to listen to what you hear. You may struggle with intense negative self-dialogue, telling yourself mean and harmful things. You may have too many voices in your head at one time. This is what many people call mental illness.
