Swami Sri Yukteswar „The Holy Science“

”What is ignorance? Ignorance, Avidya, is misconception, or is the erroneous conception of the existence of that which does not exist. Through Avidya man believes that this material creation is the only thing that substantially exists, there being nothing beyond, forgetting that this material creation is substantially nothing and is a mere play of ideas on the Eternal Spirit, the only Real Substance, beyond the comprehension of the material creation. This ignorance is not only a trouble in itself but is also the source of all the other troubles of man.”
