Drawing just one card is the easiest and probably the most common method of reading. Without a storyline like when interpreting a spread, there are no cards to compare and contrast. Simply interpret the card as the answer to the question.
Alternatively, this method may be used repeatedly in succession to allow the cards to tell a story.
This is regarded as probably the worst symbol in the deck of playing cards. This card means absolute rock bottom, a period of mental breakdown and insanity. There will be an end to misery once the walls of your delusion fall to ruins. On the bright side, there will be a moment of clarity leading to rebirth.
