Earth. A biosphere.  A complex,  subtly balanced life support system.   et turtur nidum,  ubi reponat pullos suos  altaria tua Domine virtutum,  Rex meus, et Deus meus and the turtledove a nest  where it might place its young  Your altar of strengths, Lord,  my king and my God,   We are floating over the line  Let us follow our mind  All of our life we'll wait for the answer  And the question is why   If we're following our mind  We can glide into light  No one knows if there'll be an answer  While we're morphing thru time   We are floating over the line  Let us follow our mind  All of our life we'll wait for the answer  and the question is why   We're just travellers  in endless space  If we're following our mind  We can glide into light   No one knows if there'll be an answer  While we're morphing thru time
