The key word is UNIVERSAL and NO this cannot be found in ancient spiritual traditions. the claim of ancient traditions as universal does not make it so. I know of no other ancient religions that have the specific universal principles stated clearly and specifically in the Baha'i writings, in the UDHR, and participated in the forming process of the UN as the Baha'i Faith.Shunyadragon,
The key word and notion is Universal, therefore most of the UDHR 30 articles can be found in many spiritual & rational traditions long before Baha'i.
