Anahata, the “unstruck” chakra, is the fourth of the seven principal chakras in the tantric system described in the Shat Chakra Nirupana. Located at the centre of the chest, behind the sternum, it is depicted as a twelve-petalled lotus with the seed mantra Yam, the air element (vayu tattva), and two interlocking triangles forming a hexagram. The presiding deity is Isha (a form of Shiva) and the Shakti is Kakini. The name anahata, “unstruck”, refers to the sound said to arise spontaneously at this chakra, the anahata nada, an inner sound produced without two surfaces striking each other, in contrast to all sounds in the physical world.
Source and iconography
The Sanskrit anahata means “unstruck” or “uncaused”. The Shat Chakra Nirupana, verses 28–38, gives the iconography: twelve petals inscribed with the syllables Kam, Kham, Gam, Gham, Ngam, Cham, Chham, Jam, Jham, Nyam, Tam, Tham; a six-pointed star (two interlocking triangles, one pointing up and one pointing down); the seed mantra Yam; the vehicle a black antelope, representing the swift mobility of air.
Anahata is treated in the tantric corpus as the midpoint of the chakra system. The three lower chakras (Muladhara, Svadhisthana, Manipura) are associated with the gross elements (earth, water, fire) and the worldly drives. The three upper chakras (Vishuddha, Ajna, Sahasrara) are associated with the subtler elements (ether, mind, beyond-element) and the transcendent states. Anahata sits at the meeting point, the chakra of integration between the worldly and the transcendent.
The hridaya granthi: the heart-knot
The tantric texts describe three “knots” (granthis) along the central channel that must be untied for Kundalini to rise fully: the Brahma granthi at Muladhara, the Vishnu granthi at Anahata, and the Rudra granthi at Ajna. The Vishnu granthi is the heart-knot, associated with attachment to the affections, the binding of the seeker to the world of relationships. Untying this knot in the classical reading means not the absence of love but the freeing of love from possessive grasping.
This framing distinguishes the classical Anahata practice from the modern wellness reading of the “heart chakra” as the site of emotional opening. The classical reading is more demanding: the work at Anahata is the freeing of the heart from the patterns that bind it, not the cultivation of warm feelings.
What the chakra governs
- The element of air, mobility and pervasiveness.
- The sense of touch, the air-aligned sense.
- The breath, particularly the residence of prana vayu in the chest.
- The capacity for love, devotion (bhakti), and the equanimity that allows love without grasping.
- The integration of the lower and upper energies; the meeting point of the physical and the transcendent.
Practices traditionally associated
- Yam seed mantra: chanted aloud or silently, attention at the centre of the chest.
- Hridaya pranayama: slow deep breathing with attention at the chest, often paired with the visualisation of breath flowing in and out at the heart centre.
- Bhakti practices: chanting, kirtan, and devotional repetition of names, where the affective heart-opening is the explicit aim.
- Asanas with chest opening: Bhujangasana (cobra), Ustrasana (camel), Setu Bandha (bridge), Matsyasana (fish).
- Anahata nada meditation: attention to the inner sound, the meditation on the spontaneous sound said to arise at the heart centre once the practice has matured.
- Metta-style practices: not classical hatha yoga but compatible, the directed cultivation of loving-kindness toward self, loved ones, neutral persons, difficult persons.
The anahata nada, the inner sound
The Hatha Yoga Pradipika 4.65–102 gives an extended treatment of nada anusandhana, the meditation on the inner sound. The verses describe a sequence: the practitioner sits with the ears closed (the shanmukhi mudra used in Bhramari), attention drawn inward, and gradually becomes aware of a sound that appears to arise from the heart region. The sound is described as passing through ten stages, from a faint chirping like that of crickets, through bells, conch shells, lutes, flutes, and finally a deep continuous tone.
Modern interpretations of this inner sound vary. Audiologically, the brain in a quiet environment produces a faint continuous noise floor that becomes audible when external sound is removed; the Pradipika’s description matches this experience closely. The classical reading treats the sound as a manifestation of nada Brahman, the sound-aspect of ultimate reality. Both readings are consistent with the practice.
A simple Anahata practice
- Sit upright in Sukhasana or on a chair with the spine erect.
- 5 to 10 minutes of slow nasal breathing with attention at the chest, the breath visualised as flowing in and out at the centre of the sternum.
- 10 to 15 minutes of silent repetition of Yam, attention at the heart centre.
- Optionally close with 5 minutes of nada meditation: ears closed with shanmukhi mudra, attention drawn inward to whatever sound is present.
- Sit quietly for 2 to 3 minutes before rising.
For what it’s worth, of all the chakra-specific practices, Anahata is the one most amenable to integration with daily life. The chest-centred breathing and the cultivation of equanimity in the felt sense of the heart can be done in short sessions during the day, between tasks, in a way that the more demanding practices (uddiyana bandha at Manipura, mula bandha at Muladhara) cannot.
Common questions
Is the heart chakra the same as the physical heart?
No. The Anahata chakra sits at the centre of the chest, behind the sternum, while the physical heart is slightly to the left. The two are sometimes conflated in popular writing. In the classical tantric anatomy the chakras lie along the central channel (sushumna), which runs through the spinal column; their projection onto the front of the body is for the purpose of practice and visualisation, not anatomical identity with the corresponding organ.
Why a six-pointed star at Anahata?
The hexagram (two interlocking triangles, one pointing up and one pointing down) represents the meeting of the ascending and descending energies, the integration of the masculine (Shiva) and feminine (Shakti) principles. It is also the geometric figure that the air element is associated with in the classical schema. The shape is not borrowed from any external religious tradition; it appears independently in tantric iconography.
Can a “heart chakra blockage” be diagnosed?
Not in any clinical sense. The language of “blockages” and “openings” is practitioner-internal, useful as a framework for self-assessment but not a diagnostic tool. The classical texts describe the chakras as states of practice rather than as conditions to be diagnosed. Popular books and apps that diagnose specific chakra blockages from symptoms are extrapolating well beyond what the source material supports.
How does Anahata practice relate to bhakti?
Bhakti, the path of devotion, is the practice tradition that engages the heart most directly. The devotional repetition of a divine name, the kirtan singing of bhajans, the practice of seeing the divine in all beings, all work at the heart centre. Bhakti and the classical Anahata practice are compatible and historically often combined; the Vaishnava and Shakta bhakti traditions both incorporate heart-centred meditation alongside the formal devotional repertoire.
One limitation worth noting
The modern wellness framing of the “heart chakra” as an emotional opening to be cultivated through gentle practices does not match the classical reading. The Hatha Yoga Pradipika and the Shat Chakra Nirupana treat Anahata as a difficult middle station of the Kundalini journey, the site of the Vishnu granthi that must be untied. The classical work at this chakra is demanding, not gentle, and the heart-opening is the consequence of practice rather than its starting point. Reading modern self-help material on Anahata alongside the classical sources requires keeping this difference in view.
