Chakra
Cakraचक्र· CHUK-rahwheel, disc
A chakra is an energy centre in the subtle body, traditionally described as a spinning wheel of prana along the spine.
The Sanskrit cakra means "wheel," "circle" or "disc," from a root conveying turning or revolving. Applied to the subtle body, the word pictures a focal centre where currents of prāṇa converge and turn — which is why chakras are so often described as spinning wheels of energy arranged along the spine.
A chakra is a node in the network of nāḍīs, a meeting-point where subtle energy is said to gather. Different traditions describe them with associated sounds, colours, elements and qualities of mind. The familiar system of seven, running from the base of the spine to the crown, is one influential scheme among several.
Detailed chakra schemes appear in tantric and haṭha sources; the Ṣaṭ-cakra-nirūpaṇa, a sixteenth-century text, sets out the well-known six-plus-one arrangement, while the Gheraṇḍa Saṃhitā and Haṭha Yoga Pradīpikā reference centres along suṣumnā. Earlier and regional texts list different numbers, so no single canon fixes them for all traditions.
In practice chakras serve as focal points for concentration, visualisation and breath. You might rest attention at the heart, or the space between the eyebrows, or pair a centre with a mantra. The aim is a gathered, one-pointed awareness rather than any attempt to manipulate a physical organ or gland.
Chakras belong to the subtle model, not physical anatomy; they are not glands or nerve plexuses, though popular writing sometimes conflates them. Different texts also give different numbers, so treat the seven-chakra system as one traditional map, valuable for contemplation, and not as settled fact or a medical description of the body.
Frequently asked questions
- Are there always seven chakras?
- No. Seven is the most widely known scheme, but classical texts list varying numbers — some six, some more, some fewer. The count reflects a particular tradition's map of the subtle body rather than a fixed anatomical reality, so it is best held as one framework among several.
- Do chakras correspond to organs or glands?
- That is a modern association, not the classical view. Chakras belong to the subtle-body framework, not physical anatomy. Linking them to specific glands can serve as a memory aid, but it should not be mistaken for a physiological or medical fact about the body.
