What does Book of Pots mean in Rubiayat?

The Rubaiyat Of Omar Khayyam was what brought the scent of roses and the sound of bulbuls to poetry pages. It is a book with 101 verses through which the poet expounds his philosophy. We know from the lines that the poet was prone to read, drink and write. When he reached verse 82, he decided to give his eagerly waiting Jug Of Wine a chance to speak it's philosophy too. Therefore he incorporated a separate section of 9 verses from 82 to 90 in the middle of the book, so that his inseperable companion also may speak it's policies, visions and desires. This part he named Kuza Nama or The Book Of Pots in which during Ramazan, the strict fasting month of Mohammedans, he visited a Potter's Shop in the evening before the new moon rise. There were numerous pots and vessels of all shapes and sizes there, of which Nine of them spoke their Excellent philosophies like men to the poet, one in each verse. After this portion, with 11 more verses, The Rubaiyat is closing. This portion is really a break in the continuity of sense in the poem and so is considered unimportant. A reader can certainly exclude these nine verses from the mainstream and continue reading, and enjoying. After that, he can turn to this Kuza Nama portion as an Appendix or Post Script to the main poem.
