Page of Swords
Clarify your motives before you get involved.
This card is traditionally entitled The Page, but in some modern decks appears as a Princess. The traditional interpretation is about a messenger, an emissary or liaison between separate camps, charged with faithfully representing one side's communications to the other. Because of this role, we do not think of this person as a servant, but rather as a diplomat, facilitating sensitive negotiations, often under difficult conditions.
This person is acting as the eyes and ears of her patron, and so she is sometimes referred to as The Watchman. Even kings are powerless if this messenger chooses to use her access to sensitive information for her own gain, as is implied by her other name, The Spy.
She could even be working as a double agent, playing both sides against each other to serve her own agenda. Her title is really camouflage in itself, serving as protective coloration so she can move among the people unrecognized, collecting information anonymously. Her vigilance often conceals an ulterior motive. She is a watcher who must herself be watched, because she dreams of someday taking matters into her own hands, preempting the plans of her employers.
In the Advice Position
Circumstances call for anonymous action even if you would prefer to receive credit.
The card in the Advice position suggests a course of action which will harmonize what you want with what is currently possible.
When the Page of Swords (in some decks, a Princess) is in this position, the situation requires subtle change in order for it to be brought to the highest good for all concerned. In contrast to times when one can best serve the greater good by being visible and heroic, this is a time when you must keep your own counsel, cover your tracks and stealthily accomplish what would be impossible to complete without privacy.
Reduce your profile and increase your anonymity, no matter how your self-image might suffer. Although it would be gratifying to accomplish what needs to be done and be aboveboard about it, that cannot be a priority at present.
