Answer:
I'm the source of all emotion, but I'm caged in a white prison.
Whiling away the hours of flowers, Walking through fields of gold. Preening and pruning in lights fading hours, For petals to freeze in the cold. What is it?
Die without me, never thank me. Walk right through me, never feel me. Always watching, never speaking. Always lurking, never seen.
White bird, featherless, flying out of paradise. Flying over sea and land. Dying in my hand.
I'm white, I'm round, but not always around. Sometimes you see me, sometimes you don't.
A word of five letters, Upside down is the same, A shark does this, But itβs not to blame. What is the word?
