Six lines, built from the bottom up, by either of the two classical methods. The result links straight through to the hexagram it produced and to the text of every line that moved.
This tool generates six numbers and looks up a table. It does not predict, and it knows nothing about you or your question. The link you can copy reproduces the same casting rather than a new one, which is the only sense in which any of it is fixed.
The I Ching is unusually good at describing timing and position, which is why people bring it questions of the form is now the moment rather than what will happen. It is not an answer machine, and a hexagram that reads badly is describing a situation, not issuing a verdict.
They are not the same oracle. Three coins give every line the same chance of moving: one in eight either way. The yarrow stalks do not, and their asymmetry is the older behaviour, which is why some readers hold that a change from yang is meant to be three times as likely as a change from yin. Neither is wrong. This tool shows you the odds for whichever you pick.
The casting is generated from a number that travels in the URL. Sharing the link shares that number, so whoever opens it sees the casting you saw. Press Cast again for a new one.
Then you read the Judgement and the Image of the hexagram you got, and no line text at all. A still hexagram is a complete answer, and reading line texts into it is the commonest mistake beginners make.
That is the one case with a genuine special rule, and it applies only to hexagrams 1 and 2, which have a seventh line text for exactly this situation. For every other hexagram, read the Judgement of the second hexagram.
No. The Wilhelm and Baynes text is still in copyright and is not reproduced here. The hexagram pages are written against James Legge's 1882 translation, which is in the public domain, rendered into plain English rather than pasted.
You can, and the tradition is fairly blunt about it: asking again usually means you did not like the first answer. If the second casting is meant to be useful, change the question rather than repeat it.
