Do not worry
Do not anger
Be kind to others
The above is a translation that is true to the Japanese Reiki Precepts which Reiki founder, Mikao Usui, encouraged his students to recite as part of their Reiki practice.
Hawayo Takata gave her students a different version, one she undoubtedly thought more relevant to their needs and cultural understanding (or lack of understanding).
Just for today, do not worry.
Just for today, do not anger.
Honor your parents, teachers, and elders.
Earn your living honestly.
Show gratitude to every living thing.
