From "In the House of Tom Bombadil:"
Quote:
Old Tom Bombadil is a merry fellow;
Bright blue his jacket is, and his boots are yellow.
'Fair lady!' said Frodo again after a while. 'Tell me, if my asking does not seem foolish, who is Tom Bombadil?'
'He is,' said Goldberry, staying her swift movements and smiling.
Frodo looked at her questioningly. 'He is, as you have seen him,' she said in answer to his look. 'He is the Master of wood, water and hill.'
'Then all this strange land belongs to him?'
'No indeed!' she answered, and her smile faded. 'That would indeed be a burden,' she added in a low voice, as if to herself. 'The trees and the grasses and all things growing or living in the land belong each to themselves. Tom Bombadil is the Master. No one has ever caught old Tom walking in the forest, wading in the water, leaping on the hill-tops under light and shadow. He has no fear. Tom Bombadil is master.'

Also, from "In the House of Tom Bombadil:"
Quote:
Whether the morning and evening of one day or of many days had passed Frodo could not tell. He did not feel either hungry or tired, only filled with wonder. The stars shone through the window and the silence of the heavens seemed to be round him. He spoke at last out of his wonder and a sudden fear of that silence:
'Who are you Master?' he asked.
'Eh, what?' said Tom sitting up, and his eyes glinting in the gloom. 'Don't you know my name yet? That's the only answer. Tell me, who are you, alone, yourself and nameless? But you are young and I am old. Eldest, that's what I am. Mark my words, my friends: Tom was here before the river and the trees; Tom remembers the first raindrop and the first acorn. He made paths before the Big People, and saw the little People arriving. He was here before the Kings and the graves and the Barrow-wights. When the elves passed westward, Tom was here already, before the seas were bent. He knew the dark under the stars when it was fearless--before the Dark Lord came from Outside.'

I'm afraid there is little (if any) answer beyond this text. You can explore
thread, after thread, after thread and many more threads besides these few. I don't think you'll find any more explanation than that.
Tom IS. The rest of the explanation is meant to come from inside you, yourself, I think. Tolkien is deliberately, even stubbornly, silent.
