Kundalini comes from the Sanskrit word kuṇḍalinī, which literally translates to “coiled snake.” The concept originates in ancient Indian spiritual traditions, where it describes a form of divine feminine energy believed to lie dormant at the base of the spine. Its roots stretch across thousands of years of Hindu philosophy, Tantric practice, and yogic texts, each building on the idea that a powerful latent force exists within the human body, waiting to be awakened.
The Sanskrit Roots of the Word
The adjective kuṇḍalin in Sanskrit means “circular” or “annular,” describing something ring-shaped or coiled. A related noun, kuṇḍa, means “bowl” or “water-pot” and appears as the name of a serpent deity in the Mahabharata, one of India’s great ancient epics. By the 8th century, the Tantrasadbhava Tantra used the term kundalī to mean “she who is ring-shaped.” By the 12th century, the word was being used directly as a noun for “snake” in historical chronicles. All of these uses circle back to the same image: something coiled, spiraling, and serpentine.
Philosophical Origins in Shaktism and Tantra
The deeper origin of kundalini as a spiritual concept lies in Shaktism, a major tradition within Hinduism centered on the worship of Shakti, the divine feminine creative power. In this framework, Shakti is understood as the energy that underlies all of reality. Kundalini is considered a localized, personal form of that same cosmic energy, coiled and sleeping within each person.
Hindu Tantra, a system of practices designed to empower and liberate both mind and body, treats kundalini as central to spiritual progress. The idea is that this dormant energy sits at the base of the spine, and through specific practices, a person can awaken it, guiding it upward through the body toward higher states of consciousness and, ultimately, spiritual liberation. This isn’t metaphor in the traditional context. Practitioners understood it as a real energetic process happening within the body’s subtle anatomy.
Where Kundalini Lives in the Body
Traditional texts describe kundalini as residing at a point called the kanda, located in the lower body between the navel and the base of the spine. Different yogic manuals place it at slightly different spots, but they all agree it sits in the lower torso, above the anus. The Hatha Yoga Pradipika places it at the promontory of the sacrum, the bony structure at the base of the spinal column. This area is also called the mulakanda, meaning “root bulb,” referring to its role as the root support of the spinal energy system.
From this point, kundalini connects to the muladhara chakra, the lowest of the body’s energy centers. The texts describe the energy as lying there in the shape of a coiled serpent, dormant until deliberately aroused through yogic practice. Three energy channels, called nadis, play key roles in this system. Two of them, the ida and pingala, run along either side of the spine and govern opposing qualities: the ida is associated with calm, intuition, and relaxation, while the pingala relates to drive, mental focus, and physical energy. The third and most important channel, the sushumna, runs directly through the center of the spine. Kundalini’s upward journey is said to travel through the sushumna, and activating this central channel is associated with deep inner stillness and heightened awareness.
The Hatha Yoga Pradipika: A Key Text
While references to kundalini appear in earlier writings, the 15th-century Hatha Yoga Pradipika is one of the most detailed practical manuals on the subject. Written in 389 verses across four chapters, it covers physical postures, breath control, energy seals (called mudras), and the body’s subtle energy system. Its third chapter is particularly focused on kundalini, stating directly: “The goddess sleeping at the entrance of Brahma’s door should be constantly aroused with all effort by performing mudra thoroughly.”
The text lays out specific techniques. Sitting in a firm cross-legged position, the practitioner would compress the area near the kanda while performing forceful breathing exercises called bhastrika pranayama. Other instructions involve sustained breath retention, held for up to an hour and a half during morning and evening practice. These weren’t gentle relaxation exercises. They were intense physical disciplines aimed at generating enough internal force to awaken the dormant energy and push it upward through the spine.
How Kundalini Reached the West
Kundalini remained largely within Indian spiritual traditions until the early 20th century. A pivotal moment came in 1932, when the Swiss psychiatrist Carl Jung delivered a series of lectures on kundalini yoga to the Psychological Club in Zurich. These talks are widely regarded as a milestone in the Western psychological understanding of Eastern thought. Jung didn’t approach kundalini as a literal energy to be awakened. Instead, he used the chakra system as a model for the developmental phases of higher consciousness, interpreting its symbols through the lens of his theory of individuation, the process by which a person becomes a more integrated self.
Jung’s lectures raised important questions that still resonate: What is the relationship between Eastern schools of liberation and Western psychotherapy? What light do kundalini’s symbols shed on extreme psychological states? By framing complex Indian concepts within Western psychological language, Jung made the idea accessible to an entirely new audience and opened the door for decades of cross-cultural interest in the practice.
Modern Scientific Perspectives
There is no scientific consensus that kundalini energy exists as described in traditional texts. However, some of the physical practices associated with it do produce measurable effects. Research published in Scientific Reports found that yogic breathing techniques, the same category of breathwork used in kundalini practice, increased the power and velocity of cerebrospinal fluid flow in the skull by 16 to 28 percent compared to normal breathing. Cerebrospinal fluid cushions the brain and spinal cord, distributes nutrients and hormones, and helps remove metabolic waste from the central nervous system.
Deep abdominal breathing produced the strongest effect, shifting the primary driver of fluid movement from heart pulsation to respiration itself. This finding suggests that the intense breathing exercises described in texts like the Hatha Yoga Pradipika may genuinely alter the fluid dynamics surrounding the brain and spinal cord. Whether this mechanism explains the subjective experiences practitioners have reported for centuries remains an open question, but it offers a plausible biological pathway for why these practices feel so powerful.
Some researchers have also drawn connections between kundalini’s described pathway along the spine and the vagus nerve, the longest nerve in the body, which runs from the brainstem to the abdomen and regulates heart rate, digestion, and the body’s relaxation response. The overlap between vagus nerve stimulation effects and reported kundalini experiences, including warmth, tingling, emotional release, and altered states of consciousness, has prompted interest in exploring these parallels further.
