Whenever it is said "not yet glorious," it means its dao is not yet glorious and great. The caution to find advantage in hardship and perseverance is precisely because of what it lacks, for it has not attained Central Position and Correct Position.
Six in the fifth place: Biting into dried meat, he obtains yellow gold. Persevering in awareness of danger, no blame.
The fifth line is higher up in the hexagram, yet it bites dried meat, which is actually easier than the dried gristly meat of the fourth line, because the fifth line occupies the honored position: relying on the momentum of being on high to punish those below, its momentum makes it easy.
But being near the hexagram's culmination, the obstruction is very large and not easy to bite through; hence it is biting dried meat. "Obtains yellow gold": yellow is the color of the center, and metal/gold is a firm substance.
The fifth line dwelling in the center attains the central dao; occupying a firm place while the fourth line assists it with firmness is obtaining yellow gold.
The fifth line has no proper correspondence, but the fourth line occupies the position of a great minister, so the fifth line obtains its aid.
"Persevering in awareness of danger, no blame": although Six in the fifth place occupies a central and firm position, its substance is actually yielding; therefore it is cautioned that it must be correct and steadfast, harboring a sense of danger and severity, and then it will attain freedom from blame.
When a yielding line occupies the honored position in the time of Biting Through, how could it not be steadfast and persevere, harboring danger and awe?
