In the book the meaning of the quote is more to the effect of how truly great athletes can perform on the verge of what spectators would consider inhuman or possible. I'd be hard-pressed to believe that language and syntax would be responsible for these kinds of actions and flow. I'd argue that getting into such a state is not possible while the mind is caught up in the language of things rather than the experience itself, and reacting to it directly. This is what I meant by the quiet consciousness, devoid of language or syntax.
