"I believe that for a spell to exert its power, at least two conditions are necessary."
"First is magical power. A person without magical power is a Muggle, and an animal without magical power is an ordinary animal. With magical power, a wizard can become a wizard, and a magical creature can become a magical creature."
"Magical power is authority—the key that causes a wave function to collapse in a specific direction."
"Second is will. A wizard must have a sufficiently vivid imagination of the effect they wish to achieve, as well as enough confidence and motivation to bring it about. In the world of magic, consciousness determines matter. Without the push of will, matter will simply follow its own course. A spell played from a recording will have no effect."
"On the basis of this hypothesis, I introduced a third hypothesis to explain why different wizards have different affinities for different spells."

"The multidimensional hypothesis of magical power."
"Suppose magical power has multiple dimensions, and each dimension has many levels, or tiers. They can be represented by certain numerical values. Every wizard's magical power occupies different tiers in each dimension."
"I analyzed all spells and roughly divided the dimensions of magical power into six categories: creation, protection, mind, transformation, evocation, and control. This six-dimensional method of analysis is still incomplete, but it can already break down nearly every spell into one or more of these six elements."
"When a spell's elemental composition matches a wizard's magical-power dimensions, their affinity is relatively high, and the wizard can cast that spell more easily. When the two differ greatly in dimension, it becomes more difficult to cast."
"Finally, to address why the same wizard could cast the same spell with differing levels of power, I introduced a fourth hypothesis."
