Hexagram 48 井 changing to hexagram 18 蠱
Changing lines (counted from the bottom): 5, 6.
What to read
Two changing lines: read both line texts of the original hexagram; the upper one is the main one. (Rule set out by Zhu Xi in the Yixue qimeng.)
Hexagram 48 井, line 6
井收勿幕，有孚元吉。
The topmost line, divided, shows (the water from) the well brought to the top, which is not allowed to be covered. This suggests the idea of sincerity. There will be great good fortune.
Hexagram 48 井, line 5
井冽，寒泉食。
The fifth line, undivided, shows a clear, limpid well, (the waters from) whose cold spring are (freely) drunk.
The two hexagrams
Hexagram 48 井 — judgment
改邑不改井，无喪无得，往來井井。汔至亦未繘井。羸其瓶，凶。
(Looking at) Zing, (we think of) how (the site of) a town may be changed, while (the fashion of) its wells undergoes no change. (The water of a well) never disappears and never receives (any great) increase, and those who come and those who go can draw and enjoy the benefit. If (the drawing) have nearly been accomplished, but, before the rope has quite reached the water, the bucket is broken, this is evil.
Hexagram 18 蠱 — judgment
元亨。利涉大川。先甲三日，後甲三日。
Kû indicates great progress and success (to him who deals properly with the condition represented by it). There will be advantage in (efforts like that of) crossing the great stream. (He should weigh well, however, the events of) three days before the turning point, and those (to be done) three days after it.
