Open readings address the larger aspects of your life rather than a specific problem area or question. They're usually done when you're entering a new phase of life, such as getting married, graduating from college or starting a family. You can somewhat direct the reading if you have a general area you want to cover, such as your career or health, but that's as specific as the direction gets.
Just as in any profession, mediums have specialties and areas of expertise. Unlike Allison Dubois in Medium, I don't work with the police in solving crimes. Or, unlike Melinda Gordon in The Ghost Whisperer, I don't help tormented souls cross over. Over the years, it has become very clear that my job lies in working with souls who have happily crossed over to the other side and, for the most part, are at peace. Sure, they may have regrets or unresolved issues, but they're not haunted or lost. Oftentimes, it's the living that are not at peace. The main goal of your deceased loved ones and spirit guides is to assist you in moving on, free of grief and struggle, so you can fulfill your life lessons and enjoy your time here on earth.
After drawing your cards, revisit your initial question to ensure that it has been addressed properly. A good tarot guide can help you interpret the images you see on the tarot cards, but there’s really no substitute for personal reflection. As with any skill, practice makes perfect, so use this tarot tool often (daily, if possible), or order a set of Astrology Answers Master Deck Tarot Cards and practice at home!
