Ajna is the element of light, the colour indigo blue or milky white. As we move up through the chakras we awaken, we become more aware. Ajna is about Awareness and to me that is the epitomy of Yoga, linking the body, breath and mind, which distinguishes it from just physical exercise. Yogis are wise!!!
Ajna is located at the top of the spinal cord where it meets the midbrain, behind our inner space of the mind / chiddayacash, and between the eyebrows. It is associated with our spiritual third eye, enabling us to look inward, our inner vision. This point is where the R and L optic nerves cross in the brain,so it is literally a third eye. Whilst our two physical eyes see the material world, our 6th chakra allows us to see and assess situations further, a link between our intellectual and psychic abilities, helping us to understand our thoughts, an intuitive 6th sense, so we become more sensitive and open to other ways of looking at things, recognising truth/satya. Ajna is close to the pituitary gland, our master gland controlling all the endocrine glands related to each chakra, responsible for Growth Stimulating Hormone and neurotransmitters such as serotonin, a mood stabiliser. The hypothalamus below influences temperature, food and water intake, our emotional and stress responses and aspects of memory.The hippocampus nearby is responsible for memory.
Resting our spiritual 3rd eye such as in Anahatasana pictured, rests our busy prefrontal cortex, letting go the planning, creating a clearer path to Ajna, which gives us focus, mental sharpness, commitment, clarity like Vishuddhi. We are able to ‘see’ what is important, so the clutter goes off our ‘to do’ list. 
We begin with eye and neck movements , then sitting in stillness -‘Closing the eyes of our body and opening the eyes of our mind’, aligning the chakras on the front side of our spine, the head in line with the spine, making a little nod at the top 3 vertebrae, space here, sensing a light feeling at the roof of the mouth. Our pranayama is Alternate Nadi Shodhana( ANS), creating a calm lightness, balancing our Autonomic Nervous System( ANS) ! We can add the 9 count breath to create more awareness and link with the core.
We chant the mantra Om.
Ajna chakra involves Yoga Awareness and Mindfulness.
Awareness is the ability to watch what we do giving ease and form – observing, adjusting, taking time and space, learning to take responsibility for ourselves as we are. Looking within ‘just you on your mat’, observing the body objectively,eg. awareness of keeping the head in line with the body as we twist- a busy life and stress can mask the info sent to the brain by sensory nerves all over the body, we can progressively lose touch with our selves – not taking the time to notice tiredness until it is exhaustion, muscle tension until it becomes painful and our joints stiff. Slowing down, feeling, getting in touch with the natural rhythms of the body, breath and mind,noticing alignment, good movement, balance, energy levels – feeling right and calm both on and off the mat. In yoga asanas, discerning our edge, our challenge point so we benefit, make changes but without going beyond our endpoint, being aware of the sensations in the body, going into them, modifying , adjusting, engaging deeper stabilising muscles, becoming more aware of stress which is always reflected in the body.
Mindfulness is awareness but with more emphasis on the present moment, just being. Time is flying by, our most precious resource, there is so much stimulus and info, we can never keep up, so we go faster! The antidote is slowing down,the only way to catch up, is to get caught up and stay conscious by breathing in the moment. It takes trust to be present, to let go, to just be – this is how we are meant to be, our natural state.
Our asanas lead with the spiritual 3rd eye, we stay and breathe, becoming aware of sensations in the body, learning to adjust and feel right.
As you can see Ajna can be a challenging practice, learning to go to our challenge point, modify, adjust, not go beyond our endpoint, still practising with a balance of effort /sthira and ease/ sukha.
Savasana involves relaxing first the physical body, always easier after movement, in this way the mind can become clear and still. We focused on the upper body, the head, releasing the eyes down into their sockets, letting the brain lobes rest, listening and allowing the Sounds of Nadam – cells vibrating between the ears. Inhaling lightness into the body, taking the breath up to Ajna, staying in the mind space, noticing the light and how it changes, any shapes, colours , patterns. Letting the eyes rest nowm sensing kindness and understanding for yourself….
