Was the predominance of mind beneficial?

[Buba]

Eckhart Tolle says in "The Power of Now":

"The predominance of mind is no more than a stage in the evolution of consciousness."

So did it contribute to the evolution of consciousness? To consciousness of human kind or individual person? If somebody was never preoccupied by his mind will he lag behind in terms of evolution of consciousness? 

What does Eckhart Tolle want to say here? My English is not that good, I may miss the obvious point.

I think he means that language and thinking with words is limited and won't end up solving all of our issues and we can evolve past that. I could be wrong though, I haven't read his books.

All senses are equal unless we create levels of importance for it, which would be a subjective creation. Not some objective truth.
