The skill of visualization forms a cornerstone of magic. Many spells incorporate this practice. Visualization basically means imagining something intensely enough in your mind to manifest it into reality in some form. Here is an exercise to enhance your mental flexibility for future visualization. Start by sitting or lying still, and visualizing yourself descending a spiral staircase. Keep your hand on the outer wall as you go. You may find it helpful to imagine that twelve steps take you all the way around the inner pole, just as twelve hours complete the circle of a clock face. Most people find it very challenging to visualize spiraling like this in their mind while their body remains motionless. If you can't get it right the first time, don't despair. Practice brings improvement.
