Reflectionism is a
theory employed in later Advaita Vedanta schools to explain how one primal
ignorance may affect several ignorant selves.
Reflectionism is founded on the concept of a reflection in a
mirror; although it differs from the original, it is nonetheless based on it.
Similarly, according to this argument, each individual's
ignorance is only a mirror of a basic ignorance.
Karl H. Potter's Presuppositions of India's Philosophies, published
in 1972, has further material.
