The third NINE, undivided, shows one moving his thighs, and keeping close hold of those whom he follows. Going forward (in this way) will cause regret.
'He moves his thighs:' - he still does not (want to) rest in his place. His will is set on 'following others:' - what he holds in his grasp is low.
