What can I compare with my mother? Preferably a hymn.

Ah! Mom!

If I am a beautiful little goldfish, then you are the vast blue sea, let me swim!

Ah! Mom!

If I am a deer, then you are a vast green forest. Let me run!

Ah! Mom!

If I am a lovely bird, then you are the vast blue sky, let me fly!

Ah! Mom!

If I am mortal and I am not alone, then, then you are my only backer!

Mom, you gave me life and "everything in the world"!
