"The Absolute is the original (bimba) and the world is the reflection (pratibimba) just as the moon causes many refection’s in different pools of water and the reflections differ in their clarity according to the degree of cleanliness of the water reflecting it and just as they appear to be stable or moving if the water is stable or moving, similarly, due to the nature of avidya (ignorance), the jivas (living beings) who are the reflections of the infinite, appear to have different forms and types."
-Adi Shankaracharya, commentary on the Brihadaranyaka Upanishad

"Due to ignorance, that which belongs to the mind; the agency of actions, etc, is attributed to the Self; just as attributed to the moon reflected in water are the trembling, etc, which belong to water."
-Adi Shankaracharya, Atma Bodha, verse 22
