The first NINE, undivided, shows the difficulty (its subject has) in advancing. It will be advantageous for him to abide correct and firm; advantageous (also) to be made a feudal ruler.
Although 'there is a difficulty in advancing,' the mind (of the subject of the line) is set on doing what is correct. While noble, he humbles himself to the mean, and grandly gains the people.
