It is important to remember that the meanings of the cards are symbolic.
What this means is that you will have to interpret the meaning of the card in terms of its position in the spread.
For example, if you are using the Zodiac spread and get a card in the House of Taurus (which is concerning finance) that warns of death or illness,
you will need to assume that this is a warning about your finances, not your physical health.
It is believed that most negative cards are warnings and should be treated as such with appropriate changes in current behavior.
For example, if you get a card that predicts poor health and you are a smoker, you should seriously quit smoking.
Generally speaking, any of the spreads can be used for future telling purposes. What makes them "future" oriented is a) the question "what next?" and b) the point of view from which the interpretation is made.
For this reason, it is important to discuss your purposes with the reader before a reading begins.
Often, we want to know something about our Free Fortune Telling because something is looming over us and we do not know what to do about it.
A future telling spread will give insight, warnings, and suggestions and ideally,
you should follow the implications in the cards if you entered into the reading with that in mind.
