Hexagram 33, Dùn (Retreat): Line 1
遁卦初六 · 天山遁 · 中文版
初六：遁尾，厉，勿用有攸往。
The line (Legge)
The first SIX, divided, shows a retiring tail. The position is perilous. No movement in any direction should be made.
Small Image commentary
There is 'the perilousness of the position shown by the retiring tail:' - but if 'no movement' be made, what disaster can there be?
象曰：遁尾之厉，不往何灾也。
In plain words
Retreating at the tail: danger; do not go anywhere. The first line is at the bottom, the tail end of the retreat, too late to get away. The Small Image asks what harm there could be if one does not go.
Applying it to your situation
If you realise you are a step behind and it is too late to pull out, this line suggests holding still for now. Would staying quiet be safer than rushing?
Position
A broken (yin) line in the first place, which is a yang (odd) place, so it is not in its proper place. Its partner is line 4; one is yin and the other yang, so they respond to each other.
If this line moves
With this line moving alone, Dùn changes into Hexagram 13 Tóng Rén (Fellowship). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·遁之同人.
The hexagram
Hexagram 33 Dùn (Retreat). The Judgment: Dun indicates successful progress (in its circumstances). To a small extent it will (still) be advantageous to be firm and correct.
Next: Line 2
