*The Story:*
The book is set in Babylon, the richest city in the ancient world. Two poor friends, Bansir (a chariot maker) and Kobbi (a musician), wonder why they work so hard but are still poor, while their childhood friend Arkad has become the richest man in Babylon.
They go to Arkad and ask him for his secret. Arkad says he was also poor once, but a rich moneylender taught him how to become wealthy.
Arkad shares his wisdom through simple parables:
*The 7 Cures For a Lean Purse (How to become rich):*
*1. Start thy purse to fattening:* Save at least 1/10 of everything you earn. Pay yourself first. If you earn 10 coins, live on 9.
*2. Control thy expenditures:* We all have more desires than we can afford. Budget your 9/10 and distinguish between necessary expenses and desires.
