# Kundalini yoga

Kundalini yoga (kuṇḍalinī-yoga) is a spiritual practice in the yogic and tantric traditions of Hinduism, centered on awakening the kundalini energy. This energy, often symbolized as a serpent coiled at the root chakra at the base of the spine, is guided upward through the chakras until it reaches the crown chakra at the top of the head. This leads to the blissful state of samadhi, symbolizing the union of Shiva and Shakti. Most yoga schools use pranayama, meditation, and moral code observation to raise the kundalini.
In normative tantric systems, kundalini is considered to be dormant until it is activated (as by the practice of yoga) and channeled upward through the central channel in a process of spiritual perfection. Other schools, such as Kashmir Shaivism, teach that there are multiple kundalini energies in different parts of the body which are active and do not require awakening. Kundalini is believed by adherents to be power associated with the divine feminine, Shakti. Kundalini yoga as a school of yoga is influenced by Shaktism and Tantra schools of Hinduism. It derives its name through a focus on awakening kundalini energy through regular practice of mantra, tantra, yantra, yoga, laya, haṭha, meditation, or even spontaneously (sahaja).

## History
### Name

The Sanskrit adjective kuṇḍala means "circular, annular". It occurs as a noun for "a snake" (in the sense "coiled", as in "forming ringlets") in the 12th-century Rajatarangini chronicle (I.2). Kuṇḍa, a noun which means "bowl, water-pot", is found as the name of a Naga in Mahabharata 1.4828. The Sanskrit feminine noun kuṇḍalī means "ring, bracelet, coil (of a rope)", and is the name of a "serpent-like" Shakti in Tantrism as early as the 11th century, in the Śaradatilaka.
What has become known as "Kundalini yoga" in the 20th century, after a technical term particular to this tradition, is actually a synthesis of Bhakti Yoga (devotion and chanting), Raja Yoga (meditation) and Shakti Yoga (the expression of power and energy)." However, it may include haṭha yoga techniques (such as bandha, pranayama, and asana), Patañjali's kriya yoga (consisting of self-discipline, self-study, devotion to God, dhyāna, and samādhi), tantric visualization and meditation techniques of laya yoga (known as samsketas).
Laya may mean either the techniques of yoga or (like Rāja yoga) its effect of "absorption" of the individual into the cosmic. Laya yoga, from the Sanskrit term laya (meaning "dissolution", "extinction", or "absorption"), is almost always described in the context of other Yogas such as in the Yoga-Tattva-Upanishad, the Varaha Upanishad, the exact distinctions between traditional yoga schools are often hazy due to a long history of syncretism, hence many of the oldest sources on Kundalini come through manuals of the tantric and haṭha traditions, including the Hatha Yoga Pradipika describes the qualified yogi as practicing the four yogas' to achieve kundalini awakening, while lesser students may resort solely to one technique or another: "Mantra Yoga and Hatha Yoga. Laya Yoga is the third. The fourth is Raja Yoga. It is free from duality."

### Hatha yoga

The Yoga-Kundalini Upanishad is a syncretistic yoga text related to the schools of Hatha and Mantra yoga.
Other Sanskrit texts treat kundalini as a technical term in tantric yoga, such as the Ṣaṭ-cakra-nirūpana and the Pādukā-pañcaka. These were translated in 1919 by John Woodroffe as The Serpent Power: The Secrets of Tantric and Shaktic Yoga. He identifies the process of involution and its techniques in these texts as a particular form of Tantrik Laya Yoga.
The Yoga-Kundalini Upanishad consists of three short chapters; it begins by stating that Chitta (consciousness) is controlled by Prana, and it is controlled by moderate food, postures and Shakti-Chala (I.1-2). Verses I.3-6 explain the concepts of moderate food and concept, and verse I.7 introduces Kundalini as the name of the Shakti under discussion:
    I.7. The Sakti (mentioned above) is only Kundalini. A wise man should take it up from its place (Viz., the navel, upwards) to the middle of the eyebrows. This is called Sakti-Chala.
    I.8. In practising it, two things are necessary, Sarasvati-Chalana and the restraint of Prana (breath). Then through practice, Kundalini (which is spiral) becomes straightened.

## Modern forms
### Yogi Bhajan

In 1968, Harbhajan Singh Puri, also known as Yogi Bhajan, introduced his own brand of kundalini yoga into the United States, "Kundalini Yoga as taught by Yogi Bhajan". Yogi Bhajan founded the "Healthy, Happy, Holy Organization" (3HO) as a teaching organization. Former Kundalini teacher and scholar Philip Deslippe claims that Yogi Bhajan took yogic postures and techniques, attached them to Tantric theories and Sikh mantras, synthesizing a new form of 'Kundalini' yoga. "When placed alongside the teachings of Swami Dhirendra Brahmachari and Maharaj Virsa Singh, it becomes strikingly apparent that at least in its earliest years, Yogi Bhajan's Kundalini yoga was not a distinct practice, but essentially a combination of yogic mechanics learned from the former and the Sikh-derived mantras (Ik Ongkaar, Sat Naam, Sri Waheguru) and chanting from the latter", Deslippe writes.

## Principles

Kundalini is the term for "a spiritual energy or life force located at the base of the spine", conceptualized as a coiled-up serpent. The practice of Kundalini yoga is supposed to arouse the sleeping Kundalini Shakti from its coiled base through the 6 chakras, and penetrate the 7th chakra, or crown. This energy is said to travel along the ida (left), pingala (right) and central, or sushumna nadi - the main channels of pranic energy in the body.
Kundalini energy is technically explained as being sparked during yogic breathing when prana and apana blends at the 3rd chakra (solar plexus) at which point it initially drops down to the 1st and 2nd chakras before traveling up to the spine to the higher centers of the brain to activate the golden cord - the connection between the pituitary and pineal glands - and penetrate the 7 chakras.
Borrowing and integrating many different approaches, Kundalini Yoga can be understood as a tri-fold approach of Bhakti yoga for devotion, Shakti yoga for power, and Raja yoga for mental power and control. Its purpose through the daily practice of kriyas and meditation in sadhana are described as a practical technology of human consciousness for humans to achieve their total creative potential. With the practice of Kundalini Yoga one is thought able to liberate oneself from one's Karma and to realize one's Dharma (Life Purpose). It is recommended to become free of desire or adopt vairagya before trying to arouse Kundalini. Additionally, having a guru is beneficial in Kundalini Yoga, because a guru can suggest the best method to awaken the Kundalini.

## Practice

The practice of kriyas and meditations in Kundalini Yoga are designed to raise complete body awareness to prepare the body, nervous system, and mind to handle the energy of Kundalini rising. The majority of the physical postures focus on navel activity, activity of the spine, and selective pressurization of body points and meridians. Breath work and the application of bandhas (3 yogic locks) aid to release, direct, and control the flow of Kundalini energy from the lower centers to the higher energetic centers.
Along with the many kriyas, meditations and practices of Kundalini Yoga, a simple breathing technique of alternate nostril breathing (left nostril, right nostril), are taught as a method to cleanse the nadis, or subtle channels and pathways, to help awaken Kundalini energy.
Sovatsky (1998) adapts a developmental and evolutionary perspective in his interpretation of Kundalini Yoga. That is, he interprets Kundalini Yoga as a catalyst for psycho-spiritual growth and bodily maturation. According to this interpretation of yoga, "the body bows itself into greater maturation [...], none of which should be considered mere stretching exercises".

## Controversy

There have been accusations that modern Kundalini Yoga practice and related groups including 3HO and Ra Ma are cult-like in practices, financial abuse, and sexual abuse. Practices may include the use of crystals, wearing white, and restricted diets and are tied to medicine denial and encouraging practitioners to solve medical problems with costly retreats. "Norton said students were told that any problem they had — addiction, mental-health issues, procrastination — could be solved by investing more time and money into Ra Ma events and programming. [...] Jagat's practitioners were told not to wear black because it shrinks their aura and not to wear rings on their middle fingers because it interferes with their connection to Saturn."
