When someone comes across the high priestess card in their tarot spread, this is how tarot readings can suddenly become very complex and more reliant on the subject of the reading for information than any other reading would be. For the most part, the high priestess on her own represents secrets. If you have a secret or are keeping one from someone else, then the high priestess might show up for you. If there is a secret that you know of and are desperately burning for some explanation to it, then the high priestess might show up to let you know that seeking an answer is going to become much more difficult than you had originally imagined.
For men, the high priestess is seen as a symbol for the perfect woman. The high priestess will show up in your tarot spread if you have the perfect woman already in your life, or if one of your greatest passions is the perfect woman. Conversely, if the subject who is being read is a heterosexual woman then the appearance of the high priestess in your spread usually alludes to yourself, meaning that you have attained her status. Of course nobody is perfect, but her solitary nature proves that you are currently at a state where you do not need validation from men, and can live a solitary life if you so wish. You are not dependant on anyone else and you are much stronger for it.
For some more examples related to how she might show up in a spread these top two examples of the perfect woman and the solitary woman both become especially relevant to you if she shows up in the relationship section of a four point spread. However, if she happens to show up in the financial section, this could mean that some secret is being kept from you related to your work. The other possibility is that it could mean that you are harboring a secret about your work that you are not sharing with anyone.
If the high priestess shows up in your spread in the finances area, this could mean that if you were recently considering your financial future, the answer will remain unclear. Is there some secret to making money that you were thinking of? Perhaps your finances are hanging on a thread and you are not sure whether or not you will be able to make the house payment for next month. If this is the case, then the high priestess usually lets you know that this will remain a mystery to you for now.
In relation to the high priestess appearing in the health section of a conventional tarot spread, while this does not necessarily mean you are in danger, it means that you should tread carefully with some of your future decisions about your health. Whatever you do in the future may lead to a serious health situation where the future outcome of what will happen to you is a total mystery.
