The Three Granthis -- Kundalini's Knots Along Sushumna

A granthi is a knot, in the plain physical sense of a tangle in a thread that stops it running smoothly through your fingers. Hatha Yoga and Tantric literature use the word with real precision: a granthi is not simply a chakra, a station, and it is not simply a general blockage anywhere in the body. It is specifically a constriction in Sushumna, the central channel of the subtle body, at three fixed points along its length, and its defining feature is that it stops Kundalini's ascent rather than merely slowing it. The articles on nadis and chakras and on Murccha on this site both mention the three granthis in passing, because no serious account of Kundalini's rise can avoid them entirely, but neither article stops to work through what a granthi actually is, how the texts describe the mechanics of piercing one, or where the two major textual sources, the Yoga Kundalini Upanishad and the Hatha Yoga Pradipika, actually agree and disagree on the details. That is the specific, narrow job of this article.

The Yoga Kundalini Upanishad, one of the twenty Yoga Upanishads attached to the Krishna Yajur Veda corpus, gives the fullest sequential account of what happens at each granthi. Kundalini, roused by the combined action of agni, the inner fire generated through pranayama and mula bandha, and vayu, the breath driven upward, first reaches the mouth of Sushumna and then pierces the Brahma granthi, described in the text as formed of rajas, the guna of activity and restlessness. Once pierced, she flashes upward at once, described with the simile of a streak of lightning, through the Vishnu granthi and on to the heart. The text then describes her rising through the Rudra granthi and above it to the midpoint of the eyebrows, after which she proceeds toward what the text calls the sphere of the moon at the crown. This sequence establishes the standard, most widely taught correspondence used across modern hatha yoga instruction: Brahma granthi at the base of Sushumna, corresponding to Muladhara; Vishnu granthi at the heart, corresponding to Anahata; Rudra granthi at the eyebrow centre, corresponding to Ajna. This is the scheme used elsewhere on this site, in the articles on nadis and chakras and on kundalini, and it is the scheme most yoga teacher trainings present as settled fact.

It would be dishonest to present the granthi scheme as though every classical text agrees on it down to the last detail, and the Hatha Yoga Pradipika is itself the clearest example of the disagreement. In its second chapter, in the closing verses on Bhastrika pranayama, Svatmarama states that vigorous Bhastrika breaks the three knots of the body, and names them in the same order, Brahma, Vishnu, Rudra, but the verse as rendered in Pancham Sinh's widely circulated 1914 translation locates Brahma granthi in the chest, Vishnu granthi in the throat, and Rudra granthi between the eyebrows, a placement that does not map cleanly onto the Muladhara, Anahata, Ajna scheme given in the Yoga Kundalini Upanishad. Separately, in its fourth chapter, on Samadhi, the Hatha Yoga Pradipika describes the piercing of the Brahma granthi as producing bliss and the anahata sounds, tinkling sounds resembling ornaments, associating that specific piercing with the region of the heart rather than the base. Scholars of Hatha Yoga literature generally treat this kind of variation as a real feature of the manuscript tradition rather than a simple translation error: different Hatha and Tantric texts, composed and copied across centuries and regions, did not all use a single, fixed correspondence between granthi and chakra, and the now-standard Muladhara-Anahata-Ajna mapping most modern teaching relies on owes at least as much to the systematic account given in the Yoga Kundalini Upanishad, and to the influence of Arthur Avalon's early twentieth-century synthesis in The Serpent Power, as it does to the Hatha Yoga Pradipika's own, briefer and less consistent treatment of the same three knots.

What all versions of the tradition agree on, whatever their differences over exact placement, is the basic mechanism: a granthi is not merely a location Kundalini passes through, it is a genuine obstruction that must be actively pierced, and piercing it is described as requiring more than raw pranic force. The Yoga Kundalini Upanishad's own account makes this explicit in what precedes the granthi-piercing verses: mula bandha must be applied with sustained effort, the breath must be genuinely purified through preceding practice, and the awakening described is the outcome of accumulated preparation rather than a single dramatic event arriving on its own. This is the same caution given in the article on Murccha regarding advanced kumbhakas, and it applies here with even more force, since the traditional literature consistently frames granthi-piercing as one of the more demanding stages of hatha yoga practice, traditionally undertaken only after the preliminary purifications, the shat karmas, and stable asana and pranayama practice are already well established, and traditionally guided by a teacher who can assess a student's actual readiness rather than their eagerness.
