Adam and Eve
Adam and Eve were commanded by God not to eat from the tree of knowledge - the tree that would give knowledge of values. But they were hungry.
Before the sorry moment, the happy couple were free of self-consciousness, and felt no need to cover their bodies with clothing. But upon eating the fruit their minds filled with self-serving ideas and false values. There was separation, "self" and "other" - two things instead of the One. With the birth of self-consciousness was born insecurity - and they covered their "private" parts with leaves.
I am reminded of the Buddhist sage Manjushri, who while travelling allowed a thought to arise in his mind. Immediately two iron mountains rose out of the ground to block his way.
