Hexagram 22, Bì (Grace): Line 6 (top)
贲卦上九 · 山火贲 · 中文版
上九：白贲，无咎。
The line (Legge)
The sixth NINE, undivided, shows one with white as his (only) ornament. There will be no error.
Small Image commentary
'The freedom from error attached to (the subject of) the topmost line, with no ornament but the (simple white),' shows how he has attained his aim.
象曰：白贲无咎，上得志也。
In plain words
Plain white adornment: no fault. The top line is at the far end of adornment, where ornament comes back round to simplicity; Confucius said that painting comes after the plain ground. The Small Image says at the top it achieves its aim.
Applying it to your situation
If you have been polishing things for a long time, this line suggests going back to the plain original may be best. With the ornament taken away, what would you most want to keep?
Position
A solid (yang) line in the top place, which is a yin (even) place, so it is not in its proper place. Its partner is line 3; both are yang, so they do not respond.
If this line moves
With this line moving alone, Bì changes into Hexagram 36 Míng Yí (Darkening of the Light). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·贲之明夷.
The hexagram
Hexagram 22 Bì (Grace). The Judgment: Bi indicates that there should be free course (in what it denotes). There will be little advantage (however) if it be allowed to advance (and take the lead).
