Reiki is a therapeutic practice of Japanese origin that uses hand placement to promote energetic balance, physical well-being, and emotional harmony.

It can be applied to people, environments, and even at a distance, and is recognized as an integrative practice in various contexts.

Origin of the Usui System

Reiki originated in Japan with Mikao Usui (1865–1926), who structured a system based on ethical principles, personal discipline, and energy application.

The method was later organized and expanded by two key figures:

• Chujiro Hayashi, who structured the clinical practice
• Hawayo Takata, who introduced Reiki to the West

Over time, Reiki spread worldwide and became part of complementary and integrative practices.

How Reiki Works

In traditional practice, Reiki is applied through the positioning of the hands on or near the body.

During a session, the practitioner acts as a channel, directing attention and intention to support the balance of the individual’s energy system.

This practice may contribute to:

• deep relaxation
• stress reduction
• emotional balance
• support for self-care processes

However, within the Usui System, Reiki is not limited to treating others.

Self-treatment is considered a fundamental part of the practitioner’s development.

Reiki Levels

Reiki teaching is usually structured into progressive levels of learning.

This structure is not meant to create spiritual hierarchy, but to organize maturity, responsibility, and depth of practice.

Level I — Awakening

The first level introduces the foundations of the practice.

Focus includes:

• self-treatment
• hand positions
• energy awareness
• in-person application

Level II — Transformation

The second level expands the possibilities of practice.

Here, traditional symbols are introduced:

• Cho Ku Rei
• Sei He Ki
• Hon Sha Ze Sho Nen

These function as tools for organizing intention and focus.

Level III — Realization

A stage of deeper internal development.

Includes the symbol:

• Dai Ko Myo (Great Bright Light)

This level emphasizes integration and personal growth.

Level IV — Mastery

In many Western schools, mastery includes:

• practitioner master
• teacher master

At this stage, the practitioner becomes responsible for:

• teaching
• initiating students
• preserving the method

Reiki is a Method, Not a Performance

With the popularization of Reiki, superficial interpretations have emerged.

However, in the original Usui System, Reiki is grounded in:

• discipline
• consistent practice
• personal responsibility
• emotional maturity
