Over time you must build up a relationship with your spirit guides. Your purpose in life is changing, and even if mediumship is only a hobby, your spirit guides need to adjust. Often-times you'll have a lead spirit guide who guides you the most in every day life and ensures you're staying on track according to your life plan if you have one. Different spirit guides preform different functions, for example, if you're an artist you may have an artist spirit guide who helps you while you paint. You may also have a motherly guide to help you in parenting and a business-minded guide for running a business. These are guides with certain expertise, learned during one or more previous lifetimes.
Celtic Cross Tarot card reading predicts your future by reading the cards. This is different from prophesies using calculations of date, time and year of birth. Each prediction or card selection may not indicate the same result. The accuracy depends on your intention and concentration at the time of selection. Thus, it is very important to concentrate hard to achieve the most significant outcome.
