Chakra

'wheel, circle'; Pali: cakka) is one of the various focal points used in a variety of ancient meditation practices, collectively denominated as Tantra, part of the inner traditions of Hinduism and Buddhism.

Psychological and other attributes, rainbow colours, and a wide range of supposed correspondences with other systems such as alchemy, astrology, gemstones, homeopathy, Kabbalah and Tarot were added later.

Lexically, chakra is the Indic reflex of an ancestral Indo-European form *kʷékʷlos, whence also "wheel" and "cycle" (Ancient Greek: κύκλος, romanized: kýklos).

[15] The iconography popular in representing the Chakras, states the scholar David Gordon White, traces back to the five symbols of yajna, the Vedic fire altar: "square, circle, triangle, half moon and dumpling".

White and Georg Feuerstein, have suggested that she may be a reference to kundalini shakti and a precursor to the terminology associated with the chakras in later tantric traditions.

[21] The latter, states David Gordon White, were introduced about 8th-century CE in Buddhist texts as hierarchies of inner energy centers, such as in the Hevajra Tantra and Caryāgiti.

[17] According to Gavin Flood, the ancient texts do not present chakra and kundalini-style yoga theories although these words appear in the earliest Vedic literature in many contexts.

[23][19] The 10th century Kubjikāmatatantra describes a system of five chakras which serve as the seats of five sets of divine female beings, namely the Devīs, the Dūtīs, the Mātṛs, the Yoginīs and the Khecarīs.

[5][6] The important chakras are stated in Hindu and Buddhist texts to be arranged in a column along the spinal cord, from its base to the top of the head, connected by vertical channels.

These chakras were also symbolically mapped to specific human physiological capacity, seed syllables (bija), sounds, subtle elements (tanmatra), in some cases deities, colors and other motifs.

(...) Virtually all human cultures known to us have some kind of concept of mind, spirit or soul as distinct from the physical body, if only to explain experiences such as sleep and dreaming.

"[39][40] The classical eastern traditions, particularly those that developed in India during the 1st millennium AD, primarily describe nadi and chakra in a "subtle body" context.

[41][43] Esoteric traditions in Hinduism mention numerous numbers and arrangements of chakras, of which a classical system of six-plus-one, the last being the Sahasrara, is most prevalent.

[46] Within Kundalini yoga, the techniques of breathing exercises, visualizations, mudras, bandhas, kriyas, and mantras are focused on manipulating the flow of subtle energy through chakras.

[5] In some early Buddhist sources, these chakras are identified as: manipura (navel), anahata (heart), vishuddha (throat) and ushnisha kamala (crown).

The highest practices in Tibetan Buddhism point to the ability to bring the subtle pranas of an entity into alignment with the central channel, and to thus penetrate the realisation of the ultimate unity, namely, the "organic harmony" of one's individual consciousness of Wisdom with the co-attainment of All-embracing Love, thus synthesizing a direct cognition of absolute Buddhahood.

[54] The tsa lung practice embodied in the Trul khor lineage, unbaffles the primary channels, thus activating and circulating liberating prana.

[58] It was this chakra system that was translated in the early 20th century by Sir John Woodroffe (also called Arthur Avalon) in his book The Serpent Power.

In esoteric Buddhism, it is called Sambhoga and is generally considered to be the petal lotus of "Enjoyment" corresponding to the third state of Four Noble Truths.

[61] In esoteric Buddhism, this Chakra is called Dharma and is generally considered to be the petal lotus of "Essential nature" and corresponding to the second state of Four Noble Truths.

[65] Kurt Leland, for the Theosophical Society in America, concluded that the western chakra system was produced by an "unintentional collaboration" of many groups of people: esotericists and clairvoyants, often theosophical; Indologists; the scholar of myth, Joseph Campbell; the founders of the Esalen Institute and the psychological tradition of Carl Jung; the colour system of Charles W. Leadbeater's 1927 book The Chakras,[66] treated as traditional lore by some modern Indian yogis; and energy healers such as Barbara Brennan.

[56][67] Leland states that far from being traditional, the two main elements of the modern system, the rainbow colours and the list of qualities, first appeared together only in 1977.

[56] In 1918, Sir John Woodroffe, alias Arthur Avalon, translated two Indian texts, the Ṣaṭ-Cakra-Nirūpaṇa and the Pādukā-Pañcaka, and in his book The Serpent Power drew Western attention to the seven chakra theory.

[73] Psychological and other attributes such as layers of the aura, developmental stages, associated diseases, Aristotelian elements, emotions, and states of consciousness were added still later.

[56] A wide range of supposed correspondences such as with alchemical metals, astrological signs and planets, foods, herbs, gemstones, homeopathic remedies, Kabbalistic spheres, musical notes, totem animals, and Tarot cards have also been proposed.

In various traditions, each chakra is associated with a physiological functions, an aspect of consciousness, and a classical element; these do not correspond to those used in ancient Indian systems.

In meditation, chakras are often visualised in different ways, such as a lotus flower, or a disc containing a particular deity.
