There are four aspects related to Ajna that sum up the essence of the Brow Chakra as the Light element when energy flow is balanced.
Integration - You are established in the balance of Body, Mind and Spirit.
Truth - You are established in the state where Karmic meaning of events are obvious to you.
Unboundedness - You are free from the known and the prison of past experiences.
Knowingness - You are established in the state of the omniscience, deep intuition and in the Present.
When Ajna is in balance and the energy flow is optimized, each of these states will resonate with you. You will feel calm and at ease without stress. You will feel present and mentally grounded. You will see synchronistic connection and meaning between common events and circumstances. Your lessons to learn in this life will become more clear and apparent. You will no longer hold on to past experiences and events, allowing them to color your perception of the Present.
