The 4 of Pentacles can be a card about holding on to things, people, money, or situations longer than is healthy or realistic. When this card appears in a reading, it's a sure sign that you must look carefully at what you are clinging to, and whether others are clinging to you in an unhealthy way. Relax.
In general, the 4 of Pentacles can point to anxiety/fear about money and/or a clinging to whatever it is that makes the querent feel secure. The key here is to try to realize that being anxious and grasping does NOT bring security. If any card in the Tarot relates to the old saying about "If you love something set it free…" this is the one
Career & Employment
With regard to work questions, the 4 of Pentacles says that you may be doing something you don't like just because it's putting food on the table. Jobs and situations such as this have their place, but to better your situation, you must elevate your spiritual understanding and belief in yourself. What would it take to be in a situation work wise that fulfills you? What steps would have to be made to get yourself there? Believe that such a thing is possible, then start making it happen.
Love & Relationships
The 4 of Pentacles is a card about fear, basically, when it comes to love. Either you are holding on far too tight to a situation or lover, or someone is attempting to do that to you. This clinging is not healthy. True love allows for space between the lovers, and no matter what, one can never really control another person. If you are single and think that you are ready for a relationship, realize that you will undoubtedly have to step outside your comfort zone to make it happen. True love will not just drop out of the sky.
Finances & Income
You have some understandable anxiety about money and are trying to hold on to every penny. There is a fine line between fear-based grasping and being accountable and deliberate about where your money goes. You can break this grip of fear by reminding yourself that no matter what your circumstances, there is someone who is less fortunate than you are. Try giving a little, with an open heart, even if it's 25 cents. Often this can open up the flow of prosperity and bring even more financial security back to you. We are all in this life together
Mental & Physical Health
The 4 of Pentacles can indicate that you need to let go of old wrongs and wounds in order to move forward. It also can mean that others are trying to hold on to you and your health in ways that are not good for you or them. Help your loved ones to see the truth, which is that not everything is in our conscious control. Meditation, particularly around issues of freedom and relaxation, is useful now.
This is a time that you must look within yourself thoroughly for the places where you are grasping and/or fearful, trying to hold onto things. Non-attachment is also freedom. Learn about the energy centers in the body and meditate on how yours are functioning. Be open to change, as change is the only constant in life. Start where you are.
