The Sphinx as the cause of the problem: The Sphinx suggests discrete observation. It suggests that you behave like a wise person who knows more than they hear, but who keeps that information to themselves until the time is right. Are you having problems keeping information that you should keep to yourself… to yourself?
Because of this Sphinx is associated with the ability to keep secrets, but at the same time manage to wheedle them out of other people. Do you need to be aware of this, is it a warning to keep your mouth closed and your ears open?
Another aspect of the Sphinx in this position is that it can represent indiscretion, inattentiveness, reticence, impatience, and cruelty caused by indifference.
