Hexagram #25 has a few very interesting names: Innocence, Without Embroiling, or The Unexpected. These are very different names for this same hexagram.
This hexagram offers a warning that now is the time to remain unentangled, to not get caught up in things (hence the name “without embroiling”). If you can do this, then you’ll be in a position to act spontaneously and confidently — which is where I think the other two names of this hexagram come from. This can begin a new time. However, if you are not able to refrain from getting caught up in things, then nothing you do will be correct.
The trigrams that make up this hexagram are thunder under heaven, which implies to me that you will be able to act powerfully if you maintain your connection to heaven. The nuclear hexagram is #53, Gradual Advancing, which suggests that if you are able to remain free from entanglements, you will be able to advance gradually towards your goal.
The first changing line says that you are free of entanglements and should proceed forward. The second changing line says that it’s not the time to expand your project, and realizing this will be to your benefit. The third changing line warns that something unfortunate has happened, but advises that it’s your choice if you want to suffer or gain from this occurrence. The fourth changing line encourages you to move ahead with your plan. The fifth changing line says that you have experienced a setback, but should allow it to run its course so you may learn from it. The sixth changing line warns that you have become entangled, and that there is nothing you can do at this time that will be of benefit.
