The question in the title is akin to asking where the equation of motion of a free falling object $a + bt + 1/2 gt^2$ in 3-space come from? then discovering that the "objects fall with constant acceleration" rule. Similarly, we derive Seiberg-Witten equations (which also have a linear part and a quadratic part) from the deformation equations of an "isotropic associative submanifold" of a complex $G_2$ Manifold. For this, we will define the notion of complex $G_2$ manifold and notion of complexification of a $G_2$ manifold (this is a joint work with Ustun Yildirim).
