Understanding the Tradition
Every practice has roots.
Before learning how to place your hands, work with symbols, offer Reiki to another person, or eventually teach Reiki yourself, it is worthwhile to pause and consider where this tradition comes from and what spirit lies at its heart.
The Reiki taught in this manual is rooted in the Usui Reiki tradition, associated with Mikao Usui in Japan in the early twentieth century.
Reiki has since developed through different teachers, lineages, cultures, and communities around the world. As a result, terminology, practices, symbols, attunement methods, and teaching approaches can vary between Reiki schools.
Understanding this distinction is important.
There is not necessarily one single presentation of every Reiki practice used by every teacher today. When you encounter differences between this manual and other Reiki teachings, you do not need to assume that one tradition must automatically invalidate the other.
Instead, learn to recognize the lineage and context from which a teaching comes.
Mikao Usui and the Origins of Usui Reiki
Mikao Usui (1865–1926) is generally recognized as the founder of the Reiki system that became known as Usui Reiki.
Usui lived in Japan during a period of significant social and cultural change. Accounts of his life and the development of Reiki have been told and retold through different sources and lineages, and some popular stories about his life contain details that are difficult to independently verify.
For this reason, it is useful to distinguish between historical information, traditional accounts, and later interpretations.
According to the commonly transmitted Reiki tradition, Usui undertook a period of intensive spiritual practice on Mount Kurama in Kyoto. Following this experience, he developed and taught a system of spiritual practice that came to be known as Usui Reiki.
Usui established a practice and teaching community in Japan and trained students who continued the tradition after his death.
Among his students was Chujiro Hayashi, who became an important figure in the transmission and development of Reiki. Hayashi later taught Hawayo Takata, who played a major role in bringing Reiki to the West.
Through these and other teachers, Reiki continued to develop and spread internationally.
The history is therefore not simply a story of one person creating a finished system and passing it unchanged through generations.
It is also a story of transmission.
Teachers received teachings.
They practised them.
They taught others.
And different lineages developed.
Understanding this history can help us approach Reiki with both appreciation and discernment.
Reiki as Universal Life-Force Energy
The word Reiki is commonly understood as being formed from two Japanese terms:
rei — often translated in contexts of Reiki as spiritual, universal, or sacred
ki — commonly understood as life-force energy
Translations and interpretations vary, and the Japanese concepts behind these terms have a richer history than any single English translation can fully express.
Within the Reiki tradition, Reiki is commonly understood as a form of universal life-force energy.
Many cultures have traditions that include concepts resembling life force or vital energy, although these concepts are not necessarily identical to one another.
Examples include qi or chi in Chinese traditions and prana in Indian traditions.
These similarities can be useful for contemplation, but they should not be treated as proof that all of these traditions describe exactly the same concept.
For the purposes of this manual, Reiki is approached within its own historical and spiritual context.
Beyond the Individual Self
The idea of universal life-force energy also opens a deeper question:
What does it mean to understand ourselves as part of something larger than the individual self?
In everyday life, we naturally experience ourselves as separate individuals.
We have our own bodies.
Our own thoughts.
Our own memories.
Our own names and stories.
Yet we are also continuously connected with the world around us.
We breathe the atmosphere.
We depend upon the living world.
We are shaped by relationships.
We participate in communities.
We exist within the larger rhythms of nature and the cosmos.
From a spiritual perspective, Reiki can become an invitation to explore this interconnectedness more deeply.
The practice may gradually shift attention away from the idea of the isolated individual and toward a sense of relationship, connection, and oneness.
This does not require you to adopt a particular metaphysical belief.
Instead, it can be explored through direct experience.
When you become still during Reiki practice, what happens to your usual sense of separation?
Can you notice the body without treating it as something completely separate from the surrounding environment?
Can you notice thoughts without assuming that every thought defines who you are?
Can awareness simply be present without needing to divide experience into categories?
These questions lead naturally toward the exploration of non-duality.
Non-duality does not necessarily mean that individual differences disappear.
Rather, it invites us to question whether the divisions through which we ordinarily organize experience tell the whole story of existence.
For some practitioners, this becomes one of the deepest dimensions of a spiritual Reiki practice.
Intention, Presence, and Non-Attachment
Reiki practice is often associated with intention.
You may begin a practice with an intention such as:
“I give myself this time to rest and reconnect.”
Or:
“May this practice support my wellbeing in whatever way is appropriate.”
Intention provides direction.
But intention does not give us control over the outcome.
This distinction is important.
There is a difference between:
setting an intention
and
demanding a result.
A self-care-centred Reiki practice emphasizes the first.
You can create the conditions for stillness.
You can offer your attention.
You can practise with sincerity.
But you cannot guarantee exactly what will happen.
This is where non-attachment becomes an important spiritual principle.
Non-attachment does not mean indifference.
It does not mean that you stop caring.
It means allowing an experience to unfold without becoming overly dependent upon a particular result.
You can care deeply while remaining open.
You can have an intention without trying to control the universe.
You can offer Reiki without deciding in advance what another person’s experience should be.
This attitude will become increasingly important as you learn to practise Reiki with others.
The Five Reiki Principles
The Five Reiki Principles are among the most recognizable teachings associated with Usui Reiki.
They are commonly presented in English in a form similar to:
Just for today, do not anger.
Just for today, do not worry.
Be grateful.
Do your work honestly.
Be kind to every living thing.
Different Reiki lineages and translations use different wording.
The wording itself is less important than engaging sincerely with the principles as a daily practice.
The phrase “just for today” is particularly meaningful.
It brings the principles out of the realm of abstract ideals and into the present moment.
You do not need to promise yourself that you will never become angry again.
You do not need to guarantee that you will never worry.
Instead, you can ask:
What would it mean to practise this principle today?
And tomorrow, you can begin again.
Just for Today
The opening phrase, “Just for today,” offers a gentle approach to practice.
It reduces the pressure of trying to transform your entire life at once.
You have today.
You have this moment.
You have this breath.
You can practise now.
This principle also connects naturally with mindfulness and presence.
When the mind becomes absorbed in regret about the past or anxiety about the future, returning to the present can create a different relationship with experience.
The present moment does not require you to solve your entire life.
It asks only that you notice where you are now.
Do Not Anger
Anger is a natural human emotion.
The principle is not an instruction to suppress anger or pretend that difficult emotions do not exist.
Instead, it can be approached as an invitation to examine our relationship with anger.
When anger arises, can we notice it before automatically acting from it?
Can we create space between an emotion and our response?
Can we understand what the emotion is communicating without allowing it to determine every action?
Anger can provide information.
It can reveal that something feels unjust, painful, threatening, or important.
The practice is not necessarily to eliminate anger.
It is to develop greater awareness around it.
Do Not Worry
Worry is also a familiar part of human experience.
The principle does not require us to pretend that uncertainty does not exist.
Instead, it invites us to notice when the mind becomes trapped in repetitive anticipation.
Ask yourself:
Is there something I can do right now?
If there is, take the appropriate action.
If there is not, can you return your attention to the present?
This is not a denial of legitimate concerns.
It is an invitation to distinguish between useful attention and repetitive mental suffering.
Reiki practice can provide a quiet space in which this distinction becomes easier to observe.
Be Grateful
Gratitude can shift attention toward what is present rather than focusing exclusively on what is missing.
This does not mean forcing yourself to feel grateful when you are experiencing pain or difficulty.
Spiritual practice should not require you to deny genuine suffering.
Instead, gratitude can be simple.
You might appreciate:
- a quiet morning;
- a supportive person;
- a moment of rest;
- sunlight through a window;
- the natural world;
- your ability to practise;
- or simply the experience of being alive.
Gratitude can be small.
It does not need to be dramatic.
Do Your Work Honestly
Honesty can be understood both externally and internally.
Externally, it may mean approaching your responsibilities with sincerity and integrity.
Internally, it may mean being honest about your own experience.
If you are distracted during Reiki practice, you can acknowledge that.
If you are uncertain, you can acknowledge that.
If you do not know the answer to someone’s question, you can say so.
If you are not qualified to provide a particular form of advice, you can refer the person elsewhere.
Integrity does not require perfection.
It requires honesty.
As a Reiki practitioner, this becomes especially important.
Do not present yourself as having abilities, knowledge, or qualifications that you do not possess.
Do not turn uncertainty into false certainty.
Do not use spiritual language to create authority where none exists.
Be Kind to Every Living Thing
The final principle extends compassion beyond the individual self.
Kindness can be directed toward other people, animals, nature, and the wider living world.
This principle also connects naturally with the idea of interconnectedness.
If we understand ourselves as participants in a larger web of life, compassion can become less about following an external rule and more about recognizing relationship.
Kindness does not mean allowing harmful behaviour to continue without boundaries.
It does not mean sacrificing yourself for everyone else.
It does not require you to agree with everyone.
You can maintain boundaries while remaining compassionate.
You can say no while remaining kind.
You can protect yourself while respecting another person’s humanity.
The Principles as a Daily Practice
The Five Reiki Principles are not intended to become a list against which you judge yourself.
You will become angry.
You will worry.
You will forget gratitude.
You will sometimes struggle with your responsibilities.
You will sometimes lose patience with others.
This is part of being human.
The practice is to notice.
Then return.
Return to the principle.
Return to the present.
Return to awareness.
This is why the phrase “Just for today” can be so powerful.
Every day offers another opportunity to practise.
Reiki as a Path of Practice
Reiki is sometimes described as a healing system, but the word healing can mean different things.
In this manual, we use the concept of healing primarily in the context of self-care, personal practice, spiritual exploration, and wellbeing, rather than as a promise to cure or treat medical conditions.
A Reiki practice can invite you to become more attentive to yourself.
It can create space for reflection.
It can encourage compassion.
It can provide a structure for meditation and intentional stillness.
And, for those drawn to its deeper spiritual dimensions, it can become an exploration of interconnectedness, oneness, and the nature of the self.
You do not need to decide in advance where your practice will lead.
Allow your understanding to develop.
Practice: Contemplating the Five Principles
Before moving on, choose a quiet moment and read the Five Reiki Principles slowly.
Rather than trying to memorize them immediately, choose one principle that feels particularly relevant to you today.
Sit comfortably.
Take a few natural breaths.
Place your hands in Gassho if that feels comfortable.
Then consider:
What would this principle look like in my life today?
Do not search for a perfect answer.
Simply notice what arises.
You might write a few sentences afterward.
Over time, you can return to the same principle and notice whether your relationship with it changes.
Reflection
Consider the following questions:
- What does Reiki mean to me at this point in my journey?
- What does the idea of universal life-force energy mean to me?
- How do I understand the relationship between the individual self and the larger whole?
- What does oneness mean to me?
- What does non-attachment mean in the context of Reiki practice?
- Which of the Five Reiki Principles feels most relevant to my life right now?
- How could I practise “Just for today” rather than expecting myself to change everything at once?
- How can I remain open to spiritual experience while maintaining discernment?
There is no requirement to reach a particular spiritual conclusion.
The purpose of Reiki practice is not to force yourself into a belief.
It is to create space for practice, observation, inquiry, and direct experience.
