Integrity means doing the right thing (even when no one is looking) - when we don't do whats right we steal from ourselves or others.
Non-stealing is one of the primary principles of a peaceful life -- not stealing money, objects, ideas, time, peace, happiness, growth, etc. And it also includes only doing honest work that does rob people of their money, health, and happiness.
Ask yourself, 'what is the right thing to do in this moment?' --- if you don't follow what you know is right you are stealing from yourself or someone else in some way, shape, or form.
How is your relationship with Integrity? Can you hear the guidance?
