Why do you believe the bible does not teach power meditation?

Sure it says meditate on the word of god. But why does it not teach breathing exercises which impower your soul and expands consiouness which many believe is the spirit. Could it be that the writers of the bible do not want you powerful? The bible I believe is hindering he true mission of our creator. Our creator wants us all to evolve our spirits... the writers of the "holy" books want it kept with only a select few.
