That Magic is increased with every magical act performed
As Favret Sara Saada observes, “Any kind of contact between the strong and the weak….. whether it operates through speech, sight, or touch, provides a loss of force or wealth in the bewitched .
Requesting a magical act of a magical practitioner results in a loss of power as the request exposes the weakness of the subject and the possible risk of further bewitchment.
P.G Maxwell Stuart observes in this relationship a correspondence with status or loss of face, but suggests the real interest in the obligation created through this performance is the potential for the loss or gain of power in- itself.
