Source of Golden Rule quote

Hayy and thank you for being here. I have heard quotes of the Golden Rule, which is the foundation of all religions. The Buddist one I received was "Hurt not others in ways that you yourself would find hurtful." I don't know where the person found this... can you help me please? The words I heard the person saying a source for their quote was "Yudana Varga"... this provides NO RESULTS! Thank you for your attention and help. _/\_ ZubinNur (The Netherlands)
