Reading the Tarot
Tarot readings can offer a different perspective on past events, and current circumstances and can also help to reveal future options. However the outcome given in a reading is not set in stone. Many people also use the Tarot for insight into specific personal situations, but they can also be used to give an understanding of the higher realms of human consciousness.
If you'd like to get a feeling for how the Tarot works, The Rider-Waite Deck or the Universal-Waite Deck are good choices for beginners. Both are available at most metaphysical and even some general bookstores. Follow the instructions given and ask simple questions to start. It's a good idea to take notes on what you've read about the cards and compare notes as to how accurate they are to your experience.
More complex readings, especially those concerning strong emotional situations or survival issues, are best left to a professional reader. Experienced Tarot readers practice and study for years to refine their skills and can guide you through the complex interactive interpretations of a spread.
Before you start reading cards for others, do lots of readings for yourself. Read books on the topic, and have your cards read by other professional Tarot readers who can help you with the symbology and meaning of the cards. It takes a great deal of responsibility to do any kind of reading for another person. People take advice on life matters very seriously, and you could cause some serious damage with a speculative or poorly educated reading, so be wise before you advise.
