Ajna and the mind
So, ajna is essentially the chakra of the mind, representing a higher level of awareness. Whenever you concentrate on something, whether it is mooladhara, swadhisthana or manipura chakra, or you concentrate on an external object or an idea, ajna is affected, sometimes mildly, sometimes powerfully, depending on the degree of your concentration. When we visualize or when we dream at night, the inner vision that occurs is through ajna. If you are eating, sleeping or talking and you are not aware of it, then ajna is not operating. But if you are talking and one area of your awareness knows it, this knowing, this awareness is the faculty of ajna. When you develop ajna, you can have knowledge without the aid of the senses. Normally, all knowledge comes to us by means of information the senses conduct to the brain, and a process of classification, logic and intellect that takes place in the frontal brain. However, the smaller brain, where ajna chakra is situated, has the capacity to acquire knowledge directly without the aid of the indriyas or senses. Supposing it is a very cloudy day, you can know, through logic, that it will rain. But if there are no clouds in the sky and still you know beyond a doubt that it will rain, this means your intuition and perception are very acute and ajna chakra is functioning.
When ajna is awakened, fickleness of the individual mind disperses and the purified buddhi (subtle intelligence or higher perception) manifests. Attachment, which is the cause of ignorance and lack of discrimination drops away, and sankalpa shakti (willpower) becomes very strong. Mental resolves are almost immediately converted into fruits, provided they are in accordance with individual dharma.
Cause and Effect
Up until ajna chakra awakens, we are under delusions, we view things incorrectly and we have many great misconceptions, about love and attachment, hatred and jealousy, tragedy and comedy, victory and defeat, and so many things. Our fears are unfounded, so are our jealousies and attachments, but still we have them. Our mind is functioning within a limited sphere and we can’t transcend it.
