Ajna , or third-eye chakra, is the sixth primary chakra in the body according to Hindu tradition. It is supposedly a part of the brain which can be made more powerful through meditation, yoga and other spiritual practices, just as a muscle is. In Hindu tradition, it signifies the subconscious mind, the direct link to the brahman. While a person’s two eyes see the physical world, the third eye is believed to reveal insights about the future. The third eye chakra is said to connect people to their intuition, give them the ability to communicate with the world, or help them receive messages from the past and the future.
It is known as the gateway to liberation
The Ajna chakra is located in the brain, directly behind the eyebrow center. Its activation site is at the eyebrow region, in the position of the “third eye.”
Ajna’s kshetram, or superficial location, is believed to be between the eyebrows at the bridge of the nose. The pineal gland deep inside the brain is also associated with Ajna in Hindu tradition, as both are considered a “third eye”. The location makes it a sacred spot where Hindus apply a vermilion bindito show reverence for it.
Ajna is described as a transparent lotus flower with two white petals, said to represent the nadis (psychic channels) Ida and Pingala, which meet the central Sushumna nadi before rising to the crown chakra, Sahasrara. The letter “ham” (हं) is written in white on the left petal and represents Shiva, while the letter “ksham” (क्षं) is written in white on the right petal and represents Shakti. These two petals also represent the manifest and the unmanifest mind, which are sometimes said to represent the pineal and pituitary glands.
Inside the pericarp of the flower is the hakini Shakti. It is depicted with a white moon, six faces, and six arms holding a book, a skull, a drum, and a rosary, while making the gestures associated with granting boons and dispelling fears. The downward-pointing triangle above her contains a white lingam. This triangle, along with the lotus flower, can represent wisdom. In some systems the deity Ardhanarishvara, a hermaphrodite form Shiva-Shakti, resides within the lingam and symbolizes the duality of subject and object.This sixth chakra of our energy body is also connect with sixth layer of aura which known as celestial layer of aura science.
