ACIM Quote 1057 A Course in Miracles Quotes
"Spirit is therefore unalterable because it is already perfect, but the mind can elect what it chooses to serve. The only limit put on its choice is that it cannot serve two masters. If it elects to do so, the mind can become the medium by which spirit creates along the line of its own creation. If it does not freely elect to do so, it retains its creative potential but places itself under tyrannous rather than Authoritative control. As a result it imprisons, because such are the dictates of tyrants. To change your mind means to place it at the disposal of true Authority."
