Lama Thubten Yeshe said,
" Imperfect superstition brings forth all the wrong delusional fantasy view, and is the obstacle to discovering perfect wisdom. Ignorance makes transmigrating beings afflicted because it obscures seeing the right view. 'Imperfect superstition', is the term Lama used for ignorance. He also called our anger, attachment belligerence, spite and other afflictions 'superstition'. We Westerners went trotting up to Kopan in Nepal and we think we are not superstitious, and then Lama said, " You bet!". That's because superstition is when you believe something exists that doesn't exist. Since we believe that there's a solid, concrete person even though such a person does not exist, we are hallucinating or being superstitious. When we believe that there's a solidly existent person who is completely evil, who's our real enemy, that's superstition. This superstition - the wrong fantasy view of ignorance, attachment and other afflictions - is an obstacle to discovering perfect wisdom. That ignorance makes transmigrating beings
( beings who go though the series of twelve links, getting born, getting old, getting sick and dying) afflicted, because it obscures their seeing the right view, the reality, how things are. So Lama was talking about the disadvantage of ignorance. Now you can see why ignorance is symbolized by a blind person in the drawing of the Wheel of life. When we are ignorant, when we're blind, we don’t understand things. We don't understand who we are. We don't understand how we exist. We don't understand how phenomena exist. We completely misinterpret things and hallucinate all the time. "
