What has become known as “Kundalini yoga” in the 20th century, after a technical term peculiar to this tradition, is actually a synthesis of many traditions which may include haṭha yoga techniques (such as bandha, pranayama, and asana), Patañjali’s kriya yoga (consisting of self-discipline, self-study, and devotion to God), tantric visualization and meditation techniques of laya yoga (known as samsketas), and other techniques oriented towards the ‘awakening of kundalini’.Laya may refer both to techniques of yoga, and (like Raja 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 Goraksha Paddhati, the Amaraugha-Prabodha, and the Yoga-Shastra of Dattatreya.The exact distinctions between traditional yoga schools is often hazy due to a long history of syncretism, hence many of our oldest sources on Kundalini come through manuals of the tantric and haṭha traditions such as the Hatha Yoga Pradipika and the Shiva Samhita. The Shiva Samhita 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.”
The Sanskrit adjective kuṇḍalin means “circular, annular”. It does occur 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 with the meaning “bowl, water-pot” is found as the name of a Naga in Mahabharata 1.4828. The feminine kuṇḍalī has the meaning of “ring, bracelet, coil (of a rope)” in Classical Sanskrit, and is used as the name of a “serpent-like” Shakti in Tantrism as early as c. the 11th century, in the Śaradatilaka.This concept is adopted as kuṇḍalniī as a technical term into Hatha yoga in the 15th century and becomes widely used in the Yoga Upanishads by the 16th century
Principles and Methodology
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 (navel center) 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 the highest forms from 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 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).
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) is 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.
