It’s not something that can be picked up and put down on a whim. If you find out that you do have the ability and want to eventually practice as a working medium, it will take dedication, patience, and time, as it can be a physically demanding job. Mediumship has to develop and grow; you’ll find that most mediums spend their entire lives developing their abilities. One final point: you must also be ready to live a life of service.
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!
