Great Gatsby Quote? WHAT DOES THIS MEAN?

Question

"It had gone beyond her, beyond everything. He had thrown himself into it w/ a creative passion, adding to it all the time, decking it out w/ every bright feather that drifted his way. No amount of fire or freshness can challenge what a man will store up in his ghostly heart."

Answer 1

Gatsby never quite got over Daisy. He believed they werent together for all the wrong reasons, and could be if he were rich. He was almost obsessed with her, and wanted to prove so much that he could provide for her. He was very much in love with her, and got lost in the midst of it, and also started losing himself and not just her. By buying all these fancy things, he was trying to make up for what he lacked years ago. There is stil that certain emptiness, a void that hes been trying to fill ever since he lost Daisy. With that said, he is materialistic for the obvious reasons. Thing is, the void his broken heart has is so deep, that no amount of pricey things can challenge it or change it... Only Daisy.

Answer 2

It's refering to how Gatsby built up to his extravagent lifestyle bc daisy wouldn't marry him 5 years earlier bc he was too poor. At the time of the events in the book, Gatsby is living a wealthy, flamboyant lifestyle to prove that he was not poor, something that had haunted him ever since daisy married tom buchanan bc he was rich
