Reiki Principles - Reiki4all.net

To give his students an ethical foundation to work from, Usui Sensei created the 5 Reiki Principles:

Observe throughout the day, with all your effort, the arising of anger, then look deeper for its true cause.
Observe your mind throughout the day for the arising of worry and restlessness, look deeper at their roots.
Be mindful, each moment of your day, appreciating the gift of life, find the right livelihood for yourself and be honest in your work.
In your day, as you appreciate your life, be kind to yourself and to all beings.
Your mind and body will truly transform with the power of Reiki, practice daily, connect to the universal nature of mind, and develop these Reiki ideals everyday.

Here are some variations on the Reiki Principles.

The secret art of inviting happiness
The miraculous medicine of all diseases
Just for today, do not be angry
Do not worry and be filled with gratitude
Devote yourself to your work and be kind to people
Every morning and evening join your hands in prayer, pray these words to your heart, and chant these words with your mouth
