The fifth NINE, undivided, shows that with firm correctness there will be good fortune (to its subject). All occasion for repentance will disappear, and all his movements will be advantageous. There may have been no (good) beginning, but there will be a (good) end. Three days before making any changes, (let him give notice of them); and three days after, (let him reconsider them). There will (thus) be good fortune.
'The good fortune of (the subject of) the fifth NINE, undivided,' is owing to its correct position and its being in the centre.
