At the heart of Reiki practice are five guiding statements known as the Reiki principles. Mikao Usui, the founder of Reiki, developed these principles as a daily ethical framework to support healing not just of the body, but of the mind and spirit. They are sometimes called the Reiki precepts or the five ideals of Reiki.
You don’t have to be a trained Reiki practitioner to benefit from them. These principles are an invitation for anyone to live with greater awareness, compassion, and peace.
The 5 Reiki Principles
The traditional wording of the principles of Reiki, as Usui taught them, begins with the phrase “Just for today.” This framing is intentional. It keeps the practice accessible and present-focused you’re not committing to a lifetime of perfection, just to this one day.
- Just for today, I will not be angry.
- Just for today, I will not worry.
- Just for today, I will be grateful.
- Just for today, I will do my work honestly.
- Just for today, I will be kind to every living thing.
Simple words. But each one carries real depth when you sit with it.
Breaking Down Each Reiki Principle
1. Just for Today, I Will Not Be Angry
Anger is a natural emotion. This Reiki principle doesn’t ask you to suppress it. It asks you to pause before reacting. Anger often signals that a boundary has been crossed or a value has been violated. The practice here is to notice the anger, understand what it’s pointing to, and respond rather than react.
Energetically, unresolved anger is said to disrupt the flow of life force energy through the body. Working with this principle daily can help release built-up tension and support clearer energy flow.
2. Just for Today, I Will Not Worry
Worry lives in the future. It pulls your attention away from what’s actually happening right now and drains your energy. This Reiki precept invites you to return to the present moment. The only place where healing and action are actually possible.
This doesn’t mean ignoring real problems. It means trusting that you can handle what comes, and not spending energy on scenarios that haven’t happened yet. Practices like meditation and breathwork pair well with this principle to calm an anxious mind.
3. Just for Today, I Will Be Grateful
Gratitude shifts your attention from lack to abundance. This Reiki principle asks you to actively notice what is going well, in your body, your relationships, your circumstances. Even on difficult days, there is usually something small worth acknowledging.
Research in positive psychology consistently shows that regular gratitude practice improves mood, reduces stress, and increases overall well-being. Usui embedded this wisdom into Reiki long before modern science confirmed it.
4. Just for Today, I Will Do My Work Honestly
This principle is about integrity showing up fully to whatever work is in front of you. Whether that’s your career, your creative practice, your relationships, or your healing journey, this precept asks you to bring honesty and effort to it.
It also includes being honest with yourself. Are you cutting corners? Avoiding what needs to be faced? This Reiki principle is a gentle but firm call to accountability.
5. Just for Today, I Will Be Kind to Every Living Thing
Kindness extends outward to other people, to animals, to the planet. But it also extends inward. Many people are far harsher with themselves than they would ever be with a friend. This Reiki precept includes self-compassion as a core practice.
When you treat yourself with kindness, you have more capacity to offer it to others. This principle recognizes that healing is not a solo journey. We are all interconnected.
How to Use the Reiki Principles Daily
Usui recommended reciting the Reiki principles morning and evening with hands pressed together in a prayer position (Gassho). This simple ritual takes less than two minutes and sets an intentional tone for your day.
Here are a few other ways to work with them:
Journal on One Principle at a Time
Choose one principle each week and journal about it. Where does this show up in your life? Where do you find it challenging? What would shift if you applied it more consistently?
Use Them as Affirmations
Write the five principles on a card and place it somewhere visible. Your bathroom mirror, your desk, your phone wallpaper. A regular visual reminder keeps them front of mind.
Pair Them with Meditation
After a short meditation session, read through the principles slowly. Notice how you feel as you read each one. Do any of them bring up resistance? That’s often a sign of where the deepest healing work is needed.
The Reiki Principles and Your Healing Practice
Trained Reiki practitioners learn these principles as part of their foundational training. They’re not an add-on. They’re central to what Reiki is. Usui believed that healing the energy body without addressing the mind and character was incomplete.
If you’re curious about becoming a Reiki practitioner yourself, learning the principles is just the beginning. Reiki Level 1 training covers these foundations in depth alongside hands-on energy healing techniques.

Final Thoughts
The five Reiki principles are deceptively simple. “Just for today” is a phrase you can return to any time you feel overwhelmed, reactive, or disconnected. You don’t have to be perfect. You just have to try, one day at a time.
Start tomorrow morning. Press your hands together, breathe, and say them out loud. See what shifts.
