Hexagram 52, Gèn (Keeping Still): Line 1
艮卦初六 · 艮为山 · 中文版
初六：艮其趾，无咎，利永贞。
The line (Legge)
The first SIX, divided, shows its subject keeping his toes at rest. There will be no error; but it will be advantageous for him to be persistently firm and correct.
Small Image commentary
'He keeps his toes at rest:' - he does not fail in what is correct (according to the idea of the figure).
象曰：艮其趾，未失正也。
In plain words
Keeping the toes still: no fault; it is favourable to be steadfast for the long term. This hexagram uses the body to show stages of stillness; the first line is at the bottom, stopping at the very start, before straying from the right way. The Small Image says it has not lost what is right.
Applying it to your situation
If you are about to do something that may not be right, this line suggests stopping at the first step. What could you still stop now?
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; both are yin, so they do not respond.
If this line moves
With this line moving alone, Gèn changes into Hexagram 22 Bì (Grace). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·艮之贲.
The hexagram
Hexagram 52 Gèn (Keeping Still). The Judgment: When one's resting is like that of the back, and he loses all consciousness of self; when he walks in his courtyard, and does not see any (of the persons) in it,--there will be no error.
