Six in the fourth place means:
In contrast to the six in the second place, which refers to a man bent exclusively on his own advantage, this line refers to one occupying a high position and striving to let his light sine forth. To do this he needs helpers, because he cannot attain his lofty aim alone. With the greed of a hungry tiger he is on the lookout for the right people. Since he is not working for himself but for the good of all, there is no wrong in such zeal.
