chiken-in

From here on out, the purpose of the mark becomes more abstract from the concrete.
In short, it goes from being linguistically expressive to a non-verbal sense.
The Chiken Mark is based on a Buddhist mark, and I think it's easy to understand if you imagine the state of the Buddha's wisdom on your body when you concretely interpret it.
To give you a concrete example, it is a sign that you should be able to receive information even if you and I disagree with it, and that you should not let your emotions get into the information, and that you should be able to receive the information as information.
