Excerpt from Dark Days Tarot Guidebook by Emily Mundy:
I. The Magician
The Magician, associated with the number of purpose and will, acts as a bridge between the spirit and human world. Typically, this card appears when you possess creative power and energy to create a new cycle of life for yourself. You are able to utilize your talents and skills, your charm and deep concentration to manifest your desires or make a transformation. The Magician reflects that the querent has power and influence over the immediate environment and surrounding circumstances. The querent also has a magical, imaginative quality of mind—they are able to picture what they most want, in detail and color, and manifest it. Tilted right, this card illustrates the power of the mind as a tool to influence the natural forces around us; tilted left, this card urges you on the path to understanding and appreciating natural laws so you may be a more positive force in co-creating your surroundings. This card in reverse reflects misuse of individual power and egocentric control of influence.
upright: power of manifestation; creative concentration
