The 4 of Swords is a card that signifies a break (or need for a break) from normal life. This can also mean that you or someone in your life may withdraw for a time. This withdrawal is not likely to be permanent. It also occasionally means illness or time in the hospital or (even more rarely) in jail. It's a clear signifier to give people their space.
In general this card usually means that you are needing some time and space to yourself. Others may be pushing too hard for bits of your time and attention. Don't hesitate to draw boundaries for yourself or to say no. Conversely, when others say no to you, take them at their word. Pushing in this circumstance is asking for trouble.
Career & Employment
This is a great time to take some time off from work if you can (even a long weekend.) you need a break and some perspective. Things are not likely to be going as you would like them to do - don't take this personally or try to push harder. Sometimes we just need to be patient with the process. If you can't stand the need for patience, perhaps the time has come to start looking for another position.
Love & Relationships
If you are currently in a romantic relationship, you may be feeling a bit disconnected. It is important to let your partner know what is going on inside, but remember that your feelings are your own, it is not necessarily their job to try to make you feel fabulous all the time. It may be that you simply need some time apart. Don't hesitate to take it. If you're looking for love, now is not the time to push. You'd be better off getting very, very specific about exactly what you are looking for in a relationship. The time will come when you will meet someone. That time is probably not in the immediate.
Finances & Income
You may need to take a different course of action if you are behind in your payments and are not sure where the money is going to be coming from. Think through ways to bring in extra money. If you have your own business, and are owed money, step up your collections activities. If you wait for people to pay you on their own accord, you could be waiting far too long. This financial logjam will not last forever. If you can, consider a small donation to a cause that you believe in, if you can do this with joy in your heart - this often opens up the flow of prosperity in your life and, if nothing else, will help you to feel good at least for a few hours about the resources in your life.
Mental & Physical Health
This card signifies a need, in the context of health, to count your blessings. Your health may not be all that you would like it to be, on the other hand, it is doubtless better than that of many other people. Be grateful for what you have. This card can also show a need to slow down and take it easy. Pushing yourself when you are too tired can cause illness or injury. Everyone needs rest and time alone.
In the context of spirituality, this card indicates a need for space. You need time and quiet, to really get in touch with your soul and the universal energies around us all. Even if you work full time and have fourteen children, if you make it a priority, you can find a minute or two of solitude. Find it and take it. Your sanity, and your soul, is crying out for this.
