2nd December to 23rd December, Mercury transits your House XII: Personal life, privacy, and spirituality.
You are paying more attention to unspoken or hidden elements of any circumstance!
Your mind is focused on private matters and past issues - this is a time when you are least likely to speak out of turn or to express yourself freely. You are searching behind the curtain, and examining the past for answers. You are seeing all sides to any given story, and forming a definite opinion does not seem "right" for the time being. Thoughts turn to the past, and clear decision-making does not come easily.
This is a good time for research, quiet contemplation, and meditation; but do avoid getting dragged down by issues that have outgrown their worth and purpose. Examining the past in order to improve the future is certainly worthwhile, as long as you don't waste your energy on guilt.
Creative endeavours could prosper now, particularly those that draw upon the emotions or that require creative visualization skills, such as poetry, art, acting, and other such activities. You are likely to require a certain amount of solitude in order to get your thoughts together or to be mentally productive.
You are less likely to chat indiscriminately during this transit, and tend to be a little secretive or tight-lipped for the time being. This may be important, in fact, because this position is sometimes associated with the uncovering of secrets, so discretion may be in order.
It is a strong period for gaining different perspectives on problems or issues in your life, as well as for reflection and research, but not the easiest time for presenting your ideas.
