The five life principles of Mikao Usui — the Reiki Gokai

The five Reiki life principles — the Gokai of Mikao Usui — are the ethical and energetic heart of every Reiki practice. Five sentences. Every morning. Every evening. Hands in front of the heart. Attention turned inward. Not as an affirmation you talk yourself into. But as contemplation — a quiet, non-judging looking at what these sentences trigger inside you.

The life principles of Mikao Usui — the Gokai 五戒 — are among the most often quoted and the most rarely understood texts in the Reiki world. Behind the apparent simplicity sits a depth that only opens up when you read the original Japanese sources. Kanji by kanji.

That is exactly what we will do now.

Two sources, one practice 二源

There are two surviving written sources for the Usui life principles. The first is a calligraphy that appears on a well-known photograph of Mikao Usui. The second is a passage on his memorial stone, next to his grave at Saihōji temple in Tōkyō.

Both texts carry the five life principles — but they differ in length, vocabulary and depth. The calligraphy is sparse: two headings, a short introduction, the five sentences, a meditation instruction and Usui's name. The memorial stone, by contrast, embeds the life principles in a wider context that adds a whole new dimension to them.

The memorial stone uses historical key terms that carry far more meaning than what is visible at first glance. An expert in Japanese culture, history and spirituality can read layers of information out of those terms that stay hidden to the untrained eye.

The headings of the calligraphy 秘法

The first two lines of the calligraphy form the title. They tell us how the life principles are meant to work — and what they are meant to do:

The meditation instruction 合掌

After the five life principles, the calligraphy gives a precise meditation instruction. It is often skipped — yet it is the key to the actual practice:

What the memorial stone adds 碑文

The text on the memorial stone widens the life principles by one decisive dimension. It makes clear that Usui's spiritual method "should not be limited to treating ailments and unfavourable habits alone." The actual point, the stone says, is that the supernatural abilities of the natural-born self form the foundation — to perfect the spiritual heart, to keep the body well, and to live a full life.

The memorial stone describes the life principles as Shūyō 修養 — spiritual exercises that are reached through intense and continuous practice. Contemplative meditations and pilgrimages in the mountains belong to this. In this understanding, the Reiki principles are not moral suggestions. They are a concrete instrument for the transformation of mind.

Worth noting too is how the memorial stone describes the role of the master. It says the content should be passed on "in an accessible way" — using the term hikin 卑近, which says that complex Buddhist relationships should be simplified to the point where anyone can understand and apply them. That is exactly what Usui did with the Gokai: he condensed the essence of esoteric Buddhism into five simple sentences.

The five Reiki principles as energy work 氣

A secret hides inside the life principles — invisible at the surface. Every single principle points to the same thing: gather your energy. Hold it together.

Do you get tired quickly after you have been angry? Do you feel drained when you worry? That is no coincidence. When you are angry or worried, you spend energy — you let it leak out. The same happens when you are unkind to yourself or others, when you hide something, when you puff yourself up. Your energy flows out into those states, and nothing is left for what truly nourishes you.

The life principles reverse this. No anger — energy stays. No worry — energy stays in the here and now. Gratitude — turns attention toward what is. Karma practice — directs energy into spiritual growth. Kindness — opens the flow of energy outward, without exhausting it.

That is why it makes sense to practice the life principles while you are still feeling well — not only after exhaustion has already arrived. When your energy is strong, you can draw from abundance before lack sets in. Wait until exhaustion is here, and you need much more strength to return to balance.

What many people misread 誤解

The Gokai are not affirmations. You are not supposed to talk yourself into the idea that everything is fine. You are supposed to contemplate the sentences — to look at them without judgment. What happens inside you when you hear: "Today — no anger"? Is there resistance? Is there relief? Is there a moment of silence? That is contemplation.

The Gokai are also not a moral sermon. Usui was not trying to raise well-behaved people. He was passing on a practice that clears the mind, gathers energy and activates the supernatural abilities that already live in every human being. The ethical effect arrives by itself — as a side effect of a practice that touches the whole person.

And the Gokai are not a one-time act. Kyō dake wa — "on this very day today" — means: every day, freshly. Not as duty. As living encounter. The sentences do not change. But you change. And what you recognize inside them deepens with every repetition.
