That would be me doing your homework.
Google is a friend.
I love it that that many Hindu writings from many sources point to a Golden age. I do not need to have read all the scriptures to see the picture they are part of. The same Great Artist becomes apparent in all.
How about the oneness of humanity From the
Atharva Veda:
"O mankind! I ordain for you to have concordance in your heart, unanimity in your minds and freedom from hatred. Every one of you ought to love one another in every way just as the cow loves the calf just born AV 3-30-1 (sahrudhayam samanya………………… AV 3-30-1)
"O Mankind! Who are respectful to the elders possessing noble hearts, friendly, in your undertakings of acquiring wealth and walking in the same path bearing the common yoke together, be never disunited with one another, come, I make you one intentioned and one minded and each one of you speak sweetly to the other AV 3-30-5 (Jyayasva……………- AV 3-30-5)
"O Mankind! I enjoin on all of you to be mutually helping one another, to be united in your mind and to have common ideal of life for benefitting one another. Like the enlightened persons whoever take care of immortal principle (in their life) may the friendly feelings amongst you increase morning and evening" AV 3-30-7 (sadhdni chinan va: ……………………. AV 3-30-7)
How else can we do this, if we do not accept our oneness under One God?
