What are the Five Principles of Reiki

The five principles of Reiki are guidelines for conduct associated with the system developed by Mikao Usui. They show that the practice is not limited to applying energy through the hands, because it also involves the way Reiki practitioners think, manage their emotions, work, and relate to other people.

In this article, you will understand the origin of the five principles in Mikao Usui's system and the meaning of each one: just for today, do not be angry, do not worry, be grateful, and work with honesty and dedication.

Continue reading to explore each principle and understand how to apply them in daily life.

The Origin of the Five Principles in Mikao Usui's System

The five principles were incorporated by Mikao Usui into his method as a foundation for personal development. The proposal was to show that the reorganization of body and mind would not depend only on the energy received, but also on the person's conscious participation.

The Reiki tradition relates part of their formulation to the moral teachings associated with Emperor Meiji, whom Usui admired. The principles were organized as accessible guidelines, capable of being remembered and practiced during ordinary situations in life.

In the traditional text, they appear within a broader instruction: practice them in the morning and at night, with the hands joined in Gassho, reciting the words attentively. This shows that the principles were not created only to be read, but for repetition, contemplation, and daily application.

Just for Today as the Foundation of the Practice

The expression “just for today” places attention on the period a person can actually live and manage. It is not possible to change yesterday, and what will happen tomorrow will still depend on choices, circumstances, and events that are not completely defined.

When someone promises never again to feel anger or worry, they make a commitment that is difficult to sustain. By limiting the practice to the present day, the guidance becomes more concrete: during this day, the person will observe their reactions and try to respond more consciously.

This proposal also reduces guilt and perfectionism. When a person becomes unbalanced, they do not need to consider the entire path lost. They can recognize what happened, understand their reaction, and begin the practice again in the next moment.

Do Not Be Angry

The first principle guides us not to feed anger. This does not mean denying the emotion, pretending to be calm, or passively accepting unfair situations. Anger can show that a boundary has been crossed, that frustration exists, or that a particular need has not been respected.

The imbalance begins when a person remains trapped in the emotion and allows it to control words, decisions, and attitudes. Repeated anger keeps the body tense, reduces mental clarity, and increases the possibility of impulsive behavior that will produce new conflicts.

Practicing this principle means noticing irritation before acting automatically. The person can step away for a few minutes, breathe, understand the reason for the reaction, and choose a firm response without turning indignation into aggression.

Do Not Worry

Worry arises when the mind tries to anticipate problems and control situations that have not yet happened. To some extent, thinking about the future helps us plan, prevent difficulties, and prepare decisions. The problem appears when this activity becomes a constant repetition of negative possibilities.

The worried mind remains occupied with scenarios that may never happen. Even without a present danger, the body reacts as though it needed to face an immediate threat, producing tension, fatigue, and difficulty concentrating on what can actually be done.

Not worrying does not mean abandoning responsibilities. It means separating planning from anxiety. When a possible action exists, the person can take it; when it does not, continuing to repeat the problem mentally only consumes energy without changing the situation.

Be Grateful

Gratitude directs attention toward what already exists and has value. The human mind tends to notice failures, threats, and absences quickly, while positive events can be considered ordinary and pass without recognition.

Practicing gratitude does not mean ignoring suffering, accepting injustice, or claiming that everything is fine. A person can recognize a difficulty and, at the same time, notice resources, lessons, relationships, and possibilities that remain present.

When exercised daily, gratitude reduces an exclusive focus on what is lacking. The person begins to register small achievements, help received, and conditions that sustain their life, developing a more balanced perception of reality.

Work with Honesty and Dedication

The fourth principle appears in translations as work honestly, devote yourself to your work, or fulfill your duties diligently. The idea is not limited to employment, because it involves the way a person performs any activity for which they have taken responsibility.

Working honestly means not deceiving, manipulating, or seeking advantages by harming other people. It also requires recognizing limits, honoring agreements, and offering work consistent with what was promised.

Dedication should not be confused with exhaustion. The principle guides presence and responsibility, not overwork. A person seeks to do well what falls to them, without using spirituality, luck, or energy as substitutes for learning and necessary action.

Be Kind to All Beings

The fifth principle guides kindness in relationships. Some translations use “be kind to people,” while others broaden the guidance to all living beings. In both cases, the center of the teaching lies in how a person treats the life around them.

Kindness does not mean agreeing with everything or allowing abuse. It is possible to establish boundaries, end relationships, and refuse requests without humiliating, attacking, or wishing suffering upon another person. Firmness can exist without aggression.

This principle also needs to appear in small actions. Listening attentively, keeping one's word, avoiding hasty judgments, and not unloading frustrations onto other people are concrete ways to transform kindness into behavior.

How to Practice the Five Principles Every Day

The traditional practice can be performed in the morning and at night. The Reiki practitioner joins their hands in Gassho, calms the breath, and recites the principles attentively, avoiding turning them into phrases repeated mechanically.

During the day, each situation functions as an opportunity for application. Irritation makes it possible to practice balance, uncertainty makes it possible to work with worry, an ordinary experience makes it possible to exercise gratitude, a task requires dedication, and a relationship offers space for kindness.

The objective is not to achieve a perfect personality. The principles function as references for observing choices and correcting responses. When they are practiced consistently, Reiki no longer occupies only the moment of application and begins to participate in the way a person conducts their own life.

Why the Principles Sustain the Practice of Reiki

The five principles sustain Reiki because they connect energy and behavior. They remind us that a person's energy field is influenced not only by an application, but also by the way they think, react, and position themselves in life.

When these principles are practiced attentively, the person begins to notice their reactions before they become an automatic habit. This process does not require perfection, but enough presence to recognize what needs to be corrected.

For this reason, the principles should not be seen as beautiful phrases separated from the practice. They form a simple and profound foundation so that Reiki can be lived with coherence, responsibility, and continuity.
