This energy-body is known, to some degree, by some of the traditions. It is a separate energy-body from “the chakras” (some Eastern traditions use the word “chakra” to refer to any component of any energy-body).
There is another meaning of the same word (sometimes spelled differently) which can refer to a body of knowledge or other things. This page refers to the energy-body of that name. The mandala of the same name was originally used with many other components, to clean and activate the relevant energy-body but does little on its own.
A few of the images of “kalachakra” do show some sort of multiple wing-shaped structures, but are obviously illustrated by someone who does not have the awareness to see the real energy-body (since the illustrations are very different from the reality).
Structurally, there are 8 curved wing-shaped components, each with a relatively small central ovoid (as illustrated), centered approximately in the upper belly. The highest of the 8th one reaches about 1.5m above the head, and the lowest goes downwards at an angle of approximately 45 degrees.
These wing-shaped components vibrate (with a somewhat wider vibration than illustrated), and often have multiple instances vibrating at different rates.
There is also a complex component starting at around the level of the feet and going down about 1.5m, with various curved beams, partially forming an approximate box-shape. There is an equivalent structure above the head, as illustrated.
There are a series of multiple small additional ovoid structures going forward and backward from the center point, reaching to a few inches behind the back and a few inches in front of the belly.
The kalachakra connects downwards, with large components part of the way down to the bottom boundary of the universe, connecting to Morphic-fields and other components there, and can influence them. If this system, or other parts of the human, are not relatively clean, the results can be negative effects, including health problems and problems in life.
It is active in those humans on earth who have the more powerful energy-level (which results in changes to other energy-bodies too), which is currently about 270 people. A few hundred others have parts of it active, some by choice, some unknowingly, and it often causes problems in this partially active (non-ideal) condition.
When in the inactive condition (as it is for most humans on earth at this time) it can cause tension and stiffness between the shoulders).
The wing-shaped components are likely to be the source of some of the wing-shaped illustrations from ancient Egypt and other locations (although other wing-shaped concepts simply denote the ability to fly, rather than being illustrative of any structural components).
Comments in these last two paragraphs are by Max Sandor (made in 2013): Without the Kalachakra being active, the heart area can never truly be “open”. Dahn Yoga has some exercises that activate it. In Hey Shyong Fu, it opens naturally. The virtue of the so-called ‘5 Tibetan Rites’ consists of strengthening the Life-power sub-centers (especially the knees) which relate to Eshus, while pushing upon the Kalachakra in the part of the stretching Yoga. The Kalachakra relates somewhat to the Indian concept of Kali.
Kala means ‘black’ or ‘cold’ (like a corpse turning black and cold). German ‘kalt’ and from there ‘to kill’, ‘kalt-machen’ in German, and English ‘cold’ and ‘cool’. It is described as a strange metallic shade, just like the color of a corpse AND the color of the placenta (after-birth). The Kalachakra Mandala has little or nothing to do with the KaLa-Chakra.
