Dr Usui devised the following principles of Reiki, which are: 

The secret art of inviting happiness

The miraculous medicine of all diseases  

Just for today, do not anger 

Do not worry and be filled with gratitude 

Devote yourself to your work. 

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 

Usui Reiki Treatment for the improvement of body and mind
