Located between the eyebrows, when Ajna is unhealthy we cannot see what is right in front of us and our perspective is limited. Denial may influence us to keep repeating unwholesome behaviors even though we know deep inside they are not good for us. We can become overly attached to and concerned about the future and may impulsively seek out the services of seers or psychics. This is a higher energy i.e. beyond the earthly elements and when excessively focused on the future, we lose the connection to our bodies and to the moment.
Hummmmm is a sound that resonates with Ajna and stimulates it.
