‘Saadi Sherazi’ has a tale about a man, whose head was full of imagined knowledge and arrogance as a result, who went to visit ‘Koshyar‘, from a great distance. ‘Koshyar’ taught him nothing, saying: ‘You may think yourself wise, but nothing can be put into a full pot.’
If you are full of pretense, ‘Saadi‘ continues, you are in fact empty. Become empty of fruitless ideas, he teaches, so that you may come and fill with higher perceptions, and understand real meaning.
