The sixth NINE, undivided, shows the representative of penetration beneath a couch, and having lost the axe with which he executed his decisions. However firm and correct he may (try to) be, there will be evil.
'The representative of penetration is beneath a couch:' - though occupying the topmost place, his powers are exhausted. 'He has lost the axe with which he executed his decisions:' - though he try to be correct, there will be evil.
