The Reiki symbols — what they really mean

Anyone who has received an initiation into the second Reiki level knows them: the symbols. Signs you draw in the air, project onto the body, visualise from within. They carry Japanese names and at first glance feel like secret codes. But what are they really? Where do they come from? And why do they work?

The answer lives in a writing tradition more than 1,300 years old — and it is astonishingly concrete.

Siddham — the sacred script behind the symbols 悉曇

The Reiki symbols did not appear from nowhere. Their roots lie in the Siddham script 悉曇 — an ancient Indian script that travelled through China to Japan in the 7th century and became the ritual foundation of esoteric Buddhism there. Every Siddham sign represents more than a sound. It embodies a Buddha, a mantra, a cosmic force.

In Japan these signs are called Bonji 梵字 — "signs of Brahma," the divine creative force. They are carved into gravestones, written onto talismans, visualised in temple ceremonies, transmitted in initiations. A Siddham sign is not a letter. It is a vessel for spiritual force.

Why a sign is more than a picture 書

In the West we tend to read symbols as stand-ins. A heart stands for love. A cross stands for Christianity. The symbol points to something else — it is not the thing itself.

In the Shingon tradition this is fundamentally different. A Siddham sign is the force it embodies. The sign of Dainichi Nyorai is not a picture that reminds you of the cosmic Buddha. It is Dainichi Nyorai in written form. When a practitioner writes this sign, visualises it and activates it with a mantra, the force of that Buddha becomes present. This is the principle on which the Reiki symbols rest.

Calligraphy in Japan and China carries a ritual dimension barely known in the West. Through meditative, contemplative writing, forces are transferred into the calligraphy. Talismans — Ofuda 御札 — are made this way. A priest writes a sign in a state of deep concentration, and the result is not simply ink on paper. It is a charged object. The Reiki symbols work on the same principle.

The four classical symbols 四符

Most Reiki traditions know four main symbols, passed on across the different levels. Each carries a Japanese name made of Kanji — and each of those Kanji tells its own story.

What got lost in the West 失

When Reiki travelled to the West in the second half of the 20th century, the symbols came along — but their context stayed in Japan. Most Western practitioners did not know the symbols come from the Siddham script. They did not know the Kanji in the names carry deeper meanings. And they did not know that drawing a symbol in the Japanese tradition is a ritual act — not a mechanical tool.

The symbols were reduced to abstract marks. People drew them, said the name three times, and expected an effect — without understanding why it works. That works up to a point, because the force of the symbols is real. But it is like playing an instrument without knowing the music. It sounds. It just does not sound the way it could.

The symbols in Shingon Reiki 真言靈氣

In Shingon Reiki the symbols are returned to their original context. That means: each symbol is understood not just as a sign, but as a connection to a specific spiritual force. It is practiced together with its mantra. It is activated with the corresponding mudra — hand gesture. And it is received through an initiation that places the practitioner in the lineage through which the symbol has been carried for centuries.

Beyond this, Shingon Reiki knows many further symbols that are not widespread in the Western tradition. Siddham signs of the great Buddhas and Bodhisattvas. Protective signs from Kuji Kiri. Ritual calligraphies used for specific purposes. Each of these signs is transmitted in its own initiation — and each deepens the practice in its own way.

How to deepen your experience of the symbols 体験

If you have already received an initiation into the second level, you already carry the symbols within you. The initiation made the connection. Now it comes down to practice.

In Shingon Reiki we recommend practicing each symbol on its own. Take time with one symbol. Draw it slowly and consciously. Speak its name — not mechanically, but as mantra, as invocation. Feel what shifts. Each symbol has its own quality, its own atmosphere, its own feeling. Cho Ku Rei feels different from Sei He Ki. Hon Sha Ze Sho Nen opens a different space than Dai Ko Myo.

And when you are ready to go deeper: in Shingon Reiki there are initiations into the original Siddham signs that stand behind the simplified symbols. These initiations open a level of practice that goes beyond drawing symbols — into the world of Buddhist deities, of mantras, of meditation.
