We did not create spirituality
I am finding that many people believe that spirituality is something we created. They are upset by the idea of anybody experiencing spirituality without using some form of established religion.
The spirit of life is the ocean we live in. We are connected to it, not through holy scriptures, but through our very existence.
The spirit inside all of us is so much greater than we give credit to. It becomes covered by our lesser identities which we believe is who we are. The spirit inside you is revealed when your constructed identity is not.
If everything that was ever written turned to ash, and our memories were wiped clean, spirituality would still exist.
