Analysis of Fire full of diamonds

A soul was born into the new light.
They looked around and saw billions and billions of others.
They were all walking through the many doors of life.
She knew which door was her door because God stood beside it and because she was the last soul that there would ever be.
She said it is done Mother River and the new light covered the plane behind her.
She looked down at her tiny new hands, body and feet.
All the other souls had left through the doors and they had been locked behind them.
She looked back for Mother River but she had left to become the other side of forever.
She contemplated on her knees why she did not go with her this final time.
God put his hand on his newest soul and said I will be your river of life and will sustain your water of light and it will flow evermore between your heart and mine.
Eons went by and finally mother reached out to her unlocking the door to her soul.
She said Dearest soul all have returned and you have lived forever and it is time to be of Mother River once more.
But, she said, Mother you left me and I hold eternity in my hands, how can I let go of Gods.
God said I cannot return without you, and I promised not to let you go.
