Ajna, the “command” chakra, is the sixth of the seven principal chakras in the tantric system. Located at the space between and slightly above the eyebrows, it is depicted in the Shat Chakra Nirupana as a two-petalled lotus with the seed mantra Om, no associated element (it is beyond the five gross elements), and a downward triangle containing a Shiva-linga. The presiding deity is Parashiva and the Shakti is Hakini. The name ajna, “command”, refers to the chakra’s role as the seat of intuitive perception, the point at which the guru’s instruction is received in the classical model. This is also the chakra popularly called the “third eye”.
Source and iconography
The Shat Chakra Nirupana, verses 32–35, describes Ajna with unusual concision: two petals inscribed with the syllables Ham and Ksham; a circle containing a downward triangle and a Shiva-linga; the seed mantra Om (or Aum); the colour generally white or transparent. Unlike the lower chakras, no element is assigned to Ajna; the tantric reading is that the chakra transcends the five gross elements (earth, water, fire, air, ether) and represents the seat of pure perception.
The two petals are sometimes read as the meeting of ida and pingala, the lunar and solar channels, at the eyebrow centre before they merge into sushumna for the final ascent to Sahasrara at the crown. In this reading Ajna is the chakra where the duality of the body’s left and right energy currents is resolved.
What the chakra governs
- Intuitive perception, the capacity to perceive beyond the five sensory inputs.
- The mind in its discriminating function; the seat of buddhi in some classical readings.
- The merging of ida and pingala, the resolution of left-right duality before the final ascent.
- The reception of the guru’s instruction; the inner voice that recognises truth.
- In the Kundalini journey, the site of the Rudra granthi, the third and final knot that must be untied for the energy to reach Sahasrara.
Practices traditionally associated
- Trataka: the candle-gazing practice catalogued among the six shatkarmas in the Hatha Yoga Pradipika 2.31–32. Trataka focuses external sight and then internal sight at the eyebrow centre, directly engaging the Ajna region.
- Om seed mantra: chanted aloud or silently, with attention at the eyebrow centre. Audible chanting of Om engages the throat (Vishuddha) and the head (Ajna) simultaneously.
- Bhrumadhya drishti: the eyebrow-centre gaze used in seated meditation. The eyes are closed, the gaze drawn inward and upward toward the third-eye point.
- Shambhavi mahamudra: an advanced practice described in Hatha Yoga Pradipika 4.36–40 combining the eyebrow-centre gaze, internal attention, and the awareness of the seer.
- Yoga nidra: the systematic body-scan and visualisation practice in which the eyebrow centre is the anchor for several stages.
- Pranayama with attention at the eyebrow centre: Anulom Vilom or Bhramari practised with the internal gaze drawn to the third-eye point.
Trataka, the principal Ajna practice
Trataka is the most directly Ajna-engaging practice in the classical syllabus. The Hatha Yoga Pradipika 2.31 prescribes the technique: fix the gaze on a small object (typically a candle flame), without blinking, until tears flow. The duration starts at 30 to 60 seconds for beginners and builds to 5 to 10 minutes for established practitioners. After the external gazing, the eyes are closed and the after-image of the flame is held in inner vision at the eyebrow centre.
The verse credits Trataka with “removing diseases of the eyes” and “developing clairvoyance”. The first claim is partially supported by modern research on the effects of focused gazing on ocular muscle control; the second is a tradition-specific claim that the practice produces inner visual experiences over time.
The pineal gland question
Modern interpretations of Ajna often associate the chakra with the pineal gland, the small endocrine gland in the centre of the brain that produces melatonin and regulates the circadian rhythm. Descartes famously called the pineal gland the “seat of the soul”. The mapping of Ajna onto the pineal is a 20th-century association, drawing on the Theosophical tradition and on speculative neuroanatomy; it is not in the Shat Chakra Nirupana or the Hatha Yoga Pradipika.
The popular claims about “decalcifying the pineal gland” or “activating the third eye” by dietary or supplemental means are extrapolations several steps removed from any tested science. The pineal gland does calcify with age in measurable ways, but the link to subjective spiritual experience is speculative. The classical Ajna practices (Trataka, bhrumadhya drishti, Om chanting) are well-attested; the pineal-decalcification claims are not.
A simple Ajna practice
- Sit upright in a dim room with a candle placed at arm’s length, the flame at eye level.
- 5 to 10 minutes of Trataka on the candle flame, holding the gaze steady, allowing tears to flow if they do.
- Close the eyes, hold the after-image of the flame at the eyebrow centre for 2 to 5 minutes.
- 10 minutes of silent or audible chanting of Om, attention at the eyebrow centre.
- 5 minutes of unstructured sitting with bhrumadhya drishti, the eyes closed and the inner gaze drawn to the third-eye point.
Total time: 25 to 35 minutes. This is the basic Ajna protocol in the Bihar School syllabus and in most modern hatha schools.
Common questions
Is Trataka safe for the eyes?
Yes, within standard precautions. The candle flame should be steady, the room dim, the practitioner seated at arm’s length. The eyes water naturally during the practice; this is the body’s way of keeping the cornea lubricated and is not a problem. Trataka is contraindicated for active glaucoma, recent eye surgery, severe dry-eye syndrome, and epilepsy where flickering light is a trigger. For most healthy adults it is safe and is sometimes prescribed by integrative ophthalmologists for ocular muscle exercise.
What does the “third eye” actually do?
In the classical tantric model, Ajna is the seat of intuitive perception, the capacity to perceive beyond the five sensory inputs. The “third eye” name draws on the iconography of Shiva, who is depicted with a third eye in the centre of the forehead that destroys when opened. The popular modern reading of the third eye as a literal organ of clairvoyance is an embellishment; the classical reading is more modest, treating the chakra as the seat of discriminating intelligence and intuition.
How long until results appear?
Concentration improvements from Trataka, the capacity to hold the gaze and the mind on a single point, are noticeable within two to four weeks of daily 5-minute practice. Subjective shifts in clarity and intuition are reported by long-term practitioners but are hard to attribute specifically to the Ajna work as opposed to the broader meditation practice. The visionary experiences described in some popular materials are not universal and are not a reliable target.
Should Ajna be worked before the other chakras are stable?
The classical tantric sequence works the lower chakras first, building stability and groundedness, before turning to the upper chakras. Working Ajna intensively without the lower chakra preparation is discouraged in most schools; the practitioner who attempts to “open the third eye” without the supporting work at Muladhara through Vishuddha is, in the traditional reading, putting the upper structure on an unprepared foundation. The modern practice of dedicating equal time to all seven chakras in a weekly cycle is a contemporary adaptation, not the classical sequence.
For what it’s worth, a steadying observation
For what it’s worth, the simplest and most reliable Ajna practice for most people is the slow audible chanting of Om at the start and end of a daily meditation. The resonance of the syllable travels through the skull bones and produces a felt vibration in the head region; this is the simplest version of the classical practice and is fully accessible without specialised instruction.
One limitation worth noting
The modern wellness literature on the third-eye chakra contains a large amount of material that does not derive from the classical tantric sources. The pineal-gland mapping, the dietary protocols for “decalcifying” the gland, the claims about specific visionary experiences as benchmarks of practice progress, and the various third-eye “activation” sequences are 20th and 21st century elaborations that may or may not be useful but are not classical. The Shat Chakra Nirupana and the Hatha Yoga Pradipika are concise on Ajna; the modern overlay is much larger than the source material. A practitioner working with the classical material directly will find the practice simpler and the claims more modest than the popular books suggest.
