THIRD EYE CHAKRA
Ajna, meaning “command' or 'summoning”, is commonly considered as the sixth primary chakra. Ajna is positioned in the stomata directly behind the centre of the forehead. This is the seat of the mind.
There are two petals (Yoga Nadis) on each side of the lotus (Chakra) that vibrate to the Sanskrit letters:— (Ham) and (Ksham).
The central Seed Syllable (Bija) is Aum, or "Pranava Om".
Ajna (along with Bindu), is known as the third eye chakra and is linked to the pineal gland which may inform a model of its envisioning. The pineal gland is a light sensitive gland that produces the hormone melatonin, regulating sleeping and waking cycles and is also postulated to be the production site of the dimethyltryptamine, the only known hallucinogen endogenous to the human body.
The Element 'Avyakta' is present here, the primordial cloud of undifferentiated energy.
