Hexagram 46, Shēng (Pushing Upward): Line 4
升卦六四 · 地风升 · 中文版
六四：王用亨于岐山，吉无咎。
The line (Legge)
The fourth SIX, divided, shows its subject employed by the king to present his offerings on mount Kh?. There will be good fortune; there will be no mistake.
Small Image commentary
'The king employs him to prevent his offerings on mount Kh?:' - such a service (of spiritual Beings) is according to (their mind).
象曰：王用亨于岐山，顺事也。
In plain words
The king makes offerings on Mount Qi: good fortune, no fault. Mount Qi was the homeland of the Zhou, and tradition takes this as King Wen. The fourth line is yielding and correct at the bottom of the upper trigram; it serves those above and smooths the way for those rising below. The Small Image says this is going along with the course of things.
Applying it to your situation
If you stand between those above and below, this line suggests serving respectfully and paving the way for others. What door could you open for those who follow?
Position
A broken (yin) line in the fourth place, which is a yin (even) place, so it is in its proper place. Its partner is line 1; both are yin, so they do not respond.
If this line moves
With this line moving alone, Shēng changes into Hexagram 32 Héng (Duration). The Jiaoshi Yilin verse for this change (Chinese): 焦氏易林·升之恒.
A recorded case from Takashima
Sheng to Heng: fortunes rising like the morning sun: A merchant asked about his fortunes and received the fourth line of Sheng, "the king makes offerings on Mount Qi; good fortune, no fault". Takashima noted that all the lines of Sheng speak of rising except the second and fourth, which speak of offerings: to rise, one must first seek the protection of the spirits. The merchant's fortunes were rising like the morning sun.
The hexagram
Hexagram 46 Shēng (Pushing Upward). The Judgment: Sheng indicates that (under its conditions) there will be great progress and success. Seeking by (the qualities implied in it) to meet with the great man, its subject need have no anxiety. Advance to the south will be fortunate.
