Ajna chakra is the location of the third eye which is the conscience.
The two physical eyes see the past and the present, while the third eye reveals the insight of the future. The seed syllable is Aum, or “Pranava Om”, the supreme sound.
When one establishes himself in the place between the eyebrows he goes beyond all the kinds of desires that motivate life and impel one to move in many directions. All experience and ideas serve only to clarify one’s perceptions in Ajna Chakra. The plane of neutrality (Sarasvati) appears as a balance between solar and lunar energy within the body.
Ida (river Ganga, feminine, lunar) and Pingala (river Jamuna, masculine, solar) nerve energies separate from the Sushumna channel at the Muladhara chakra, intertwine up through all chakras and meet with the Sarasvati, becoming one at Ajna Chakra. This brings the sense of oneness and of unity with the cosmic laws that appear in the plane of austerity. They then again separate, running into the left and right nostrils. Negative and positive, the components of duality, become equalized in Sarasvati, leaving a state of pure music and neutrality. One now becomes one-pointed; he becomes knower of past, present and future.
Ida and Pingala are time-bound; up to the fifth chakra the yogi also is time bound, but as Ida and Pingala end here, the yogi moves into Sushumna, beyond time. He is now in a state of nondual consciousness. The activation of Ajna chakra is said to lead to psychic powers (siddhis) such as clairvoyance.
The presiding deity is Ardhanarishvara, the half-male, half-female Shiva-Shakti, symbolic of basic polarity; the right side is male and the left side, female. Ardhanarishvara stands in a lingam known as Itara Lingam. The lingam is shining white, like the color of light. The male half of Ardhanarishvara has camphor-blue skin. He holds a trident in his right hand, representing the three aspects of consciousness: cognition, conation, and affection.
The female side of Ardhanarishvara is pink. She wears a red sari, and about her neck and arms are wound shining golden ornaments. She holds a pink lotus, a symbol of purity. All duality has ceased. Shiva has total command over all aspects of the self in this plane of liberation, or moksha.
The third eye of Shiva is called sva-netra, the organ of clairvoyance. Becoming Sada-Shiva, the eternal one, Shiva is no longer separate from Shakti as a separate male entity. Devata Shiva is the granter of knowledge. This knowledge brings the breath (prana) and the mind under control of Ardhanarishvara.
The energy is Hakini. Hakini Shakti has four arms and six heads. Her skin is pale pink, and her jewelry is golden and shines with gems. Wearing a red sari, she sits on a pink lotus with her left foot raised. She imparts theknowledge of unconditional truth, the awareness of nonduality. In her hands she holds the following objects: Shiva’s damaru drum, which maintains a steady drone and leads the aspirant in his way, a skull, as symbol of detachment, a mala for japa as a centering device. her remaining right hand is posed in the mudra of granting fearlessness.
