Hexagram 14, Dà Yǒu (Great Possession): Line 1
大有卦初九 · 火天大有 · 中文版
初九：无交害，匪咎，艰则无咎。
The line (Legge)
In the first NINE, undivided, there is no approach to what is injurious, and there is no error. Let there be a realisation of the difficulty (and danger of the position), and there will be no error (to the end).
Small Image commentary
This first NINE, (undivided), of Da You shows no approach to what is injurious.
象曰：大有初九，无交害也。
In plain words
Having no dealings with what is harmful, there is no fault; keeping hardship in mind, there is no fault. The first line is at the bottom of the hexagram of great possession, not yet caught up in the troubles that wealth brings; as long as it remembers hardship, it will not go wrong. The Small Image says it has no dealings with what is harmful.
Applying it to your situation
If you have begun to gain something, this line suggests remembering it did not come easily, and staying away from temptations that would harm you. What should you keep away from now?
Position
A solid (yang) line in the first place, which is a yang (odd) place, so it is in its proper place. Its partner is line 4; both are yang, so they do not respond.
If this line moves
With this line moving alone, Dà Yǒu changes into Hexagram 50 Dǐng (The Cauldron). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·大有之鼎.
A recorded case from Takashima
Da You to Ding: a samurai-turned-merchant asks about his future: Fukae, from a samurai family of Saga, had come to Yokohama to trade in paper and lime and been ruined by a swindler. The first line of Da You, "no harmful dealings; no fault; mindful of hardship, no fault", led Takashima to say he would enter government service and rise, but must not forget today's hardship when fortune turned.
The hexagram
Hexagram 14 Dà Yǒu (Great Possession). The Judgment: Da You indicates that, (under the circumstances which it implies), there will be great progress and success.
