The Seven Chakras
A journey through the energy centers of the subtle body: from root to crown, through the texts and practices of Haṭha Yoga.
A map of the interior.
Haṭha Yoga does not work with the physical body alone. It works with the subtle body — pranamaya kosha — the energetic layer that permeates and sustains it.
Within that subtle body exist the chakras (चक्र): centers where prāṇa concentrates and distributes. The tradition describes seven principal ones, arranged along suṣumnā nāḍī, the central channel that runs along the spine. [See interactive diagram →](/en/illustrations/)
They are not physical organs you can find in dissection. They are functional structures — nodes of the energetic system where prāṇa accumulates, transforms, and radiates. Each corresponds to an element, a sense, a state of consciousness.
This journey moves from bottom to top. Just like the practice.
Just as the supreme serpent (Śeṣa) supports the earth with its mountains and forests, so Kuṇḍalinī is the support of all yoga practices.
sa-śaila-vana-dhātrīṇāṃ yathādhāro 'hi-nāyakaḥ | sarveṣāṃ yoga-tantrāṇāṃ tathādhāro hi kuṇḍalī
Kuṇḍalinī is the axis of everything. Before speaking of the chakras, one must understand that they are the rungs of a single ascent.
Śeṣa, the serpent that supports the earth in Hindu cosmology, is the image chosen. Not by chance: what sustains the visible world is invisible. What sustains all practice sleeps coiled at the base.
Mūlādhāra — the root
At the base of the spine, at the perineum. Mūla: root. Ādhāra: support.
Earth element. Seed sound LAṂ. Four petals.
Here kuṇḍalinī sleeps. Here is brahma granthi, the first energetic knot that binds consciousness to inertia and survival. Until it is pierced, kuṇḍalinī does not ascend.
Working with mūlādhāra is not "activating" something magical. It is developing stability — physical, mental, existential. Without firm roots, nothing built upward can hold.
Through the union of apāna and prāṇa, the decrease of urine and feces, even the old becomes young through constant practice of Mūla Bandha.
apāna-prāṇayor aikyaṃ kṣayo mūtra-purīṣayoḥ | yuvā bhavati vṛddho 'pi satataṃ mūla-bandhanāt
Mūla bandha acts directly on this center. By contracting the perineum, apāna — the downward current — is reversed and united with prāṇa.
The text speaks of rejuvenation. The language is literal for the tradition, symbolic for us: when energy stops dispersing downward, there is more to rise.
Svādhiṣṭhāna — the dwelling
Sacral region. Sva: own. Adhiṣṭhāna: dwelling.
Water element. Seed sound VAṂ. Six petals.
The energy of the first chakra begins here to move, to take form. It governs creativity, fluidity, what flows. If mūlādhāra is the earth that holds, svādhiṣṭhāna is the water that shapes.
Maṇipūra — the city of jewels
Navel. Maṇi: jewel. Pūra: city.
Fire element. Seed sound RAṂ. Ten petals.
The furnace of the body. Seat of digestive fire — jaṭharāgni — that transforms food into energy, experience into understanding. When this fire is weak, everything stagnates. When it burns with force, everything transforms.
Then the path of the void becomes the royal road of prāṇa; then the mind becomes supportless; then death is cheated.
prāṇasya śūnya-padavī tadā rāja-pathāyate | tadā cittaṃ nirālambaṃ tadā kālasya vañcanam
When prāṇa enters suṣumnā, the mind loses its habitual base of objects and thoughts. It is left suspended.
This occurs when the lower chakras — mūlādhāra, svādhiṣṭhāna, maṇipūra — have been worked sufficiently to stop retaining energy. The fire of maṇipūra, when it burns cleanly, drives upward.
Anāhata — the unstruck sound
Center of the chest. Anāhata: that which has not been struck.
Air element. Seed sound YAṂ. Twelve petals.
The point of balance. Three chakras below (earth, water, fire). Three chakras above (ether, mind, consciousness). Here they meet.
Anāhata is also the dwelling of nāda — the inner sound, the sound that arises without anything producing it. It is not heard with the ears. It is heard when the senses have withdrawn and the mind has quieted.
Knowing the anāhata sound, cause of all, incomparable origin of sound, blocking the ears and listening to the inner sound, the sage attains the supreme state.
ānāhataṃ śabdam aśeṣa-hetuṃ śabdasya niṣpattim anaupamyeyam | jñātvā munir yāti paraṃ padaṃ tat karṇau pidhāya ca śabdam antaḥ
Covering the ears — closing access to external sound — the sage hears the inner sound.
Anāhata is where this happens. Not in the abstract: in the physical space of the chest, when practice has developed sufficient sensitivity to perceive what was always there.
Viśuddhi — the purification
Throat. Viśuddhi: especially pure.
Ether element. Seed sound HAṂ. Sixteen petals.
The filter between what is thought and what is expressed. What passes through here comes out clean or does not come out.
In Haṭha Yoga, viśuddhi has an additional crucial technical function: it is the region where amṛta falls — the nectar distilled by sahasrāra. Without intervention, that nectar descends to maṇipūra and the fire consumes it. Jālandhara bandha — the throat lock — seals this center to retain it.
Ājñā — the command center
Between the eyebrows. Ājñā: order, command.
Mind element. Seed sound OM. Two petals.
The point where iḍā and piṅgalā converge before ascending to sahasrāra. The seat of the inner guru. The center of discernment — viveka — and the silent witness.
Awakening ājñā does not mean "opening the third eye" in an esoteric sense. It means developing the capacity to observe without reacting. To see things as they are.
Through various asanas, kumbhakas and other various practices, when the great śakti awakens, prāṇa dissolves into emptiness.
vividhair āsanaiḥ kumbhair vicitraiḥ karaṇair api | prabuddhāyāṃ mahāśaktau prāṇaḥ śūnye pralīyate
The verse summarizes the entire Haṭha Yoga system in a sequence: āsanas, kumbhakas, mudrās, and bandhas → awakening of the great śakti → dissolution of prāṇa into the void.
That void is sahasrāra.
Sahasrāra — the thousand petals
Crown. Sahasra: thousand. It is not strictly a chakra but the destination.
Here ascending kuṇḍalinī reunites with Śiva — pure consciousness, without attributes. Here the nectar of immortality is gathered and radiated. Here prāṇa dissolves.
Sahasrāra is not "activated" like the other chakras. There is no technique that opens it at will. It is the result — not the means. When practice has purified the channels, dissolved the knots, and directed prāṇa upward, sahasrāra reveals itself as what was always there.
The map is not the territory.
The seven chakras are a conceptual system — a way of speaking about what happens when energy moves. It is not about believing in them. It is about practicing enough to verify them from within.
The classical texts describe them with precision not so you will memorize them, but so you will recognize what you are already experiencing.
