The Mahã Upanishad, a Vedic scripture of Hinduism with an oral tradition dating back more than 6000 years says,
"The world is my family."

This truth is the foundation and beginning of all the
great religions.

All creatures are the family of God; and he is the most beloved of God who does most good to His family......Islam

God hath made of one blood all nations of men...Christianity

Have we not all one father? hath not one God created us?
Why do we deal treacherously every man against his brother...Judaism

All are the sons and daughters of God, good people all,
Brothers and Sisters, since created by one Father. No rooted difference is there between them....Hinduism

Do not forget that the world is one great family....Regard Heaven as your father, Earth as your mother, and all things as your brothers and sisters....Shintoism

God is the Father, Earth the Mother. With all things and in all things, we are relatives....Sioux

Compassion, understanding, forgiveness, charity, and assistance towards others is the foundation upon which all religious thought is based.
It is a Truth.
Why do we hurt one another?
It certainly can't be in the name of the one God.

If we see ourselves in others then how can we harm them.
With joy and love cherish your family.
It is our gift of love from our Beloved.

"ONENESS" by Jeffery Moses
is a wonderful book that shows that the great principles are shared by all religions.
