I am a big fan of Aesop's Fables. You can find no better material describing the movement of thought and the self (although you may need to use your imagination to do so). According to legend, Aesop was a slave in Greece during the 6th century B.C. Here is a bit from Wikipedia:
During the reign of Peisistratus he was said to have visited Athens, where he told the fable of The Frogs Who Desired a King to dissuade the citizens from attempting to depose Peisistratus for another ruler. A contrary story, however, said that Aesop spoke up for the common people against tyranny through his fables, which incensed Peisistratus, who was against free speech.
I am inclined to find truth in the contrary story. I guess I am a romantic at heart. ;)
The following story struck me in such a way, I thought it might be interesting for all of you. It brilliantly describes how thought builds the image, then...well, I don't want to give it up for you. Find out for yourself. Haha.
The Ass Carrying The Image Aesop
A certain man put an image on the back of his ass to take it to one of the temples of the town. As they went along the road, all the people they met uncovered and bowed their heads out of reverence for the image; but the ass thought they were doing it out of respect for himself, and he began to give himself airs accordingly.
At last he became so conceited he imagined he could do as he liked, and, by way of protest against the load he was carrying, came to a full stop and flatly declined to proceed any further. His driver, finding him obstinate, hit him long and hard with his stick, saying, "Oh you dunderheaded idiot! Do you suppose it has come to this, that men pay worship to an ass?"
