Across the previous sections, chakra, marma, dantian, meridians, tsa–lung–thigle, lataif, and sefirot each emerged with their own histories and functions. During the nineteenth and twentieth centuries, Asian and European traditions increasingly entered the same worlds of publishing, esotericism, and comparative study, gradually shifting some of those boundaries. Elements that once belonged to different systems began to be assembled into a new image: the human body marked by centers, pathways, colors, and psychological or spiritual functions.
The most familiar version of this image revolves around seven chakra running along the body. Each chakra has a rainbow color and a bodily region, sometimes accompanied by an endocrine gland, nerve plexus, emotion, psychological quality, element, sound, or spiritual function. The structure is now so familiar that it can easily seem ancient and complete from the beginning.
Its history, however, involved many stages of assembly.
From Tantra to the Western seven-chakra system
Indian Tantric traditions used many different chakra arrangements. Some systems described six centers together with sahasrara at the crown, while others used different numbers, locations, and functions. The familiar seven-chakra model is one branch within a much broader history of the Indian subtle body.
By the late nineteenth century, Theosophy had become an important bridge bringing chakra into Western esotericism. Helena Blavatsky and later Theosophical writers placed Indian terminology within a new framework of subtle bodies, spiritual evolution, and planes of existence. In the early twentieth century, Annie Besant, C. W. Leadbeater, Alice Bailey, and others continued to expand this framework.
Another route came through the study and translation of Tantra. The Serpent Power by Arthur Avalon (Sir John Woodroffe), published in the early twentieth century, introduced English-language readers to two Sanskrit texts on chakra and Kundalini with extensive commentary. The book strongly influenced how Western readers pictured a chakra system running through the body.
Ideas moved continuously between scholars, esoteric groups, modern Yoga, and spiritual communities during this period.
Where did the rainbow colors come from?
Chakra in Tantric texts have colors, geometry, deities, mantra, and many other attributes. The familiar red–orange–yellow–green–blue–indigo–violet sequence belongs to the modern Western history of chakra.
From around the 1930s, some Western writers and color therapists began arranging chakra according to the visible spectrum. By the 1970s, the color sequence was being combined with psychological themes such as survival, sexuality, power, love, communication, intuition, and spiritual life. By 1977, Western chakra models were combining rainbow colors with a relatively developed set of psychological associations.
Anodea Judith’s Wheels of Life, published in 1987, further popularized the pairing of chakra, rainbow colors, and psychological themes within New Age culture.
The familiar structure developed gradually through Western esotericism, color therapy, the human potential movement, New Age culture, and other modern practices.

From esoteric centers to a psychological map
During the twentieth century, writers increasingly attached psychological qualities to chakra. The centers came to be associated with themes such as survival, sexuality, personal power, love, communication, intuition, and spiritual life. Popular psychology, the human potential movement, New Age culture, and healing traditions helped carry these associations into mainstream spiritual culture.
A modern diagram might link Muladhara with safety, Anahata with love, Vishuddha with communication, or Ajna with intuition. These labels are now common within wellness culture, but they emerged much later than the Tantric chakra systems themselves.
Across the twentieth century, psychological language became increasingly common in descriptions of chakra.
Chakra and the endocrine glands
One of the most familiar modern pairings places the seven chakra alongside the endocrine glands. A common version links Muladhara with the adrenal glands, Svadhisthana with the gonads, Manipura with the pancreas, Anahata with the thymus, Vishuddha with the thyroid, Ajna with the pituitary gland, and Sahasrara with the pineal gland.
Modern authors, however, have never agreed completely on these correspondences. Muladhara has been paired with either the adrenal glands or the gonads, while Ajna and Sahasrara have sometimes traded places between the pituitary and pineal glands. Correspondence charts already appeared in several variations during the early decades of the twentieth century.
In 1928, Cajzoran Ali brought chakra and the endocrine glands together in a single model in Divine Posture Influence upon Endocrine Glands. Later authors continued to alter the pairings before such charts became a familiar feature of modern chakra diagrams.
Tantric texts predate modern endocrinology and describe chakra through a very different vocabulary. The two structures can be placed beside one another to build a symbolic or practical model. Physical proximity alone does not make a chakra an endocrine gland in anatomical terms.
When other maps join the system
Chakra became the most familiar framework, and the process of synthesis continued beyond India. Chinese dantian and meridians, Ayurvedic marma, Tibetan tsa, Sufi lataif, Kabbalistic sefirot, and many other terms began appearing together in books, courses, healing practices, and diagrams of the “energy body.”
A modern diagram may place chakra along the central axis, meridians across the body, an aura around it, dantian in the abdomen, and lataif around the chest. Each element keeps its original name, yet the finished image can make them look as though they always belonged to a single structure.
The Internet accelerated this process. Images are copied, simplified, and redrawn, while their sources can disappear after only a few rounds of reposting. Terms that once belonged to separate traditions gradually become part of a shared vocabulary for a global “energy body.”
A new system assembled from many inheritances
The modern “human energy system” has a history of its own. It developed through translation, Theosophy, Western esotericism, modern Yoga, New Age culture, popular psychology, alternative healing practices, and Internet culture. Many of its components have ancient roots, while their assembly into a single system is much more recent.
Modern practices can still carry meaning for the people who use them. History helps distinguish older inheritances from elements added later. A modern synthesis also has its own history worth studying.
Looking back across all the maps in this series, the human body is their clearest point of contact. Across many periods, people have marked it with important points, pathways, flows, and ideas about the life within it. These maps also record how different eras understood the human being, life, and the world around them.
