I haven’t used a free online Tarot reading service for quite some time. As I progressed along my own Tarot journey, and got better at reading the cards, I had no need to. There are some good services out there, Lotus Tarot, Llewellyn and Tarot.com all have excellent services, some free, some paid, but the lack of specifics in positions is always a let down, and sometimes, even when there is a “the Chariot in this position tells you to….” it’s still a little general and non-specific.
A phenomenon you will come across during Tarot card study and Tarot readings are sub-elements and contradictory elements. Mainly associated with the Rider Waite-Smith Tarot deck and decks inspired by it, at its most simplistic explanation, sub-elements are those underlying elements that are secondary to the main one normally associated with a Tarot card. They can either compliment the main element and theme of the Tarot card, or they can in fact appear contradictory.
