Cho Ku Rei: The “Power Symbol,” Explained

Published Read 7 min read

On this page

Cho Ku Rei is the Reiki symbol most practitioners use first and most often, and it is widely known by its nickname, the power symbol. In the traditional Usui system it is the symbol associated with focusing and concentrating the practice, and it is usually the first one a student meets when they reach the second level of training. This article explains what the name is commonly taken to mean, how the symbol is drawn, what it is traditionally used for, and how its form and use vary between lineages. As with everything in this guide, the “power” attributed to the symbol is described here as a traditional belief, not a measured physical effect.

The name and its common translation

Cho Ku Rei is often pronounced “choh-koo-ray.” The phrase is usually translated in Reiki teaching as something close to “place the power of the universe here,” and you will also see it rendered as “putting all the power of the universe here” or simply as the directive to focus the practice on a chosen point. These translations are interpretive rather than literal dictionary entries, and different teachers word them differently, which is one reason you will encounter several versions of the same basic idea.

The nickname “power symbol” captures the gist of how practitioners talk about it: it is the symbol they associate with turning up the intensity of their focus or, as some Japanese-influenced lineages prefer, “focusing” the practice rather than amplifying a force. Whichever wording a teacher uses, the symbol’s traditional role is to concentrate attention on a particular spot, person, or moment. That concentration is a matter of intention and ritual, not a demonstrated transfer of energy.

How the symbol is drawn

In its most familiar form, Cho Ku Rei looks like a coil or spiral attached to a straight stroke. Practitioners commonly describe it as a vertical line with a horizontal segment at the top, from which a spiral curls inward, crossing the central line several times. The result is a compact shape that is quicker to draw than the more elaborate distance symbol, which is part of why it is so frequently used.

Teachers differ on the fine points, including how many times the spiral loops and exactly where it begins. A frequently mentioned detail is the direction of the spiral: some lineages draw it one way to “increase” or concentrate and the opposite way to “clear” or release, while others do not emphasize direction at all. Because the symbols were transmitted largely by demonstration and memory, these drawing conventions are best treated as lineage-specific customs rather than a single fixed standard. There is no governing authority that certifies one rendering as the only correct one.

What it is traditionally used for

Within the tradition, Cho Ku Rei is the all-purpose focusing symbol, and teaching organizations list a wide range of customary uses for it. Practitioners describe using it to “focus” the practice over a particular area, to set or clear a space before working in it, to mark the beginning of a session, and to seal or close a session at the end. Some teachers also describe traditional uses such as blessing food or creating a sense of a protected, calm environment.

It is important to read this list as a description of customary practice, not as a menu of proven benefits. When a practitioner says the symbol “increases power” or “clears” a room, they are describing the role the symbol plays in the ritual and the intention they are setting, not an outcome that has been measured. The honest framing is straightforward: the symbol gives the practitioner a structured way to direct attention, and any relaxation a recipient feels is a genuine subjective experience rather than evidence that a physical force was concentrated.

When practitioners apply it in a session

In a typical session, Cho Ku Rei often appears at the bookends. A practitioner might trace or visualize it at the start as a way of “focusing in” and setting their intention, and again at the close as a way of marking the session complete. Many also use it in the middle, drawing or picturing it over a spot where they intend to concentrate their attention, sometimes in combination with the other symbols.

Because it is the most flexible and most frequently used of the symbols, practitioners often describe layering it with others: pairing it with the mental and emotional symbol when working with feelings, or with the distance symbol when working with someone who is not present. The exact choreography is personal and varies by training. None of these sequences is a clinical protocol; they are customary patterns within a practice whose effects beyond relaxation are not established by scientific evidence.

Variations across lineages

If you compare how two practitioners use and draw Cho Ku Rei, you may notice meaningful differences, and that variation is normal. The spelling itself shifts between sources, appearing as “Cho Ku Rei,” “Choku Rei,” and other forms, because the name was carried into English through spoken teaching. The drawing can differ in the number of spiral turns and the starting point, and the emphasis on spiral direction ranges from central in some lineages to absent in others.

These differences trace back to how Cho Ku Rei in particular was passed along. As the symbol that spread first and is drawn the most, it was reproduced by hand more often than any other, so its minor variants are especially easy to find side by side. For much of the twentieth century it was held within private teaching, and only once the symbols began appearing in print from the mid-1990s did those competing renderings of the power symbol circulate openly together. When you see a variation, it usually reflects which teacher or branch a practitioner trained in rather than one form being authentic and another being mistaken. The practical takeaway is to learn the version your own teacher uses and to recognize that other valid versions exist.

Seen as a whole, Cho Ku Rei is the workhorse of the Reiki symbol set: the first one most students learn, the one drawn most often, and the one associated in tradition with focusing and concentrating the practice. Its prominence reflects how useful practitioners find it as a way to set intention at the start, middle, and end of their work. And as with every symbol in this tradition, its significance is a matter of custom and belief, with relaxation being the real, reportable part of the experience rather than any measured concentration of energy.

Frequently Asked Questions

Can I use Cho Ku Rei before learning the other symbols?
Within the standard training sequence, Cho Ku Rei is usually the first symbol taught at the second level, so students often work with it before they are comfortable with the mental and emotional or distance symbols. Teachers commonly present it first precisely because it is the most general-purpose and the easiest to draw, so using it on its own early in second-level practice is consistent with how the tradition is taught.

Does the direction of the spiral, clockwise or counter-clockwise, matter?
This depends entirely on lineage. Some teachers attach meaning to the direction, using one orientation to “concentrate” and the other to “clear,” while other teachers and branches place no emphasis on direction at all. Because there is no single governing standard, the honest answer is that it matters in some traditions and not in others, and practitioners generally follow the convention taught in their own lineage.

Is Cho Ku Rei used outside of formal sessions?
Traditionally, yes. Practitioners describe informal uses such as setting a calm intention in a room, marking the start of self-practice, or other personal rituals. These are customary applications rather than evidence-based techniques, and they remain part of the symbol’s role as a focusing cue rather than a demonstrated tool for producing any physical result.
