IMOHO - All arrangements are meaningful, but only a few are desirable. But how do we know which are which? This may be where prayer comes in. Proper prayer acts as a sort of tuning mechanism which brings us closer to the ideal.
If the theories which suggest multiple realities are true - these prayers bring us to the reality which we seek. Through faith, tachyons, or whatever - these prayers have already been answered in at least one reality. We just have to get to the reality which we seek. If "thought" is the only thing that can move faster than the speed of light - maybe this is what prayer is.
(Of course these last few posts are only approximations of provable theories. Just starting points which probably contain many steps in the wrong direction. But as of this point - this is what I'm thinking... .)
