夢見るコトが すべてはじまり それが答えだろ 誰より遠くへ飛んで見せるよ すべての明日を貫いて
This is a passage of the the song "The Biggest Dreamer" which is the opening of digimon tamers.
I would like to know the meaning of that すべてはじまり. Is it missing a の? Is it a casual way of saying すべてのはじまり? I believe it means "Dreaming is the start of everything" but why isn't there a の?
