`Prisoner, tell me, who was it that bound you?' `It was my master,'said the prisoner. `I thought I could outdo everybody in the world in wealth and power, and I amassed in my own treasure-house the money due to my king. When sleep overcame me I lay upon the bed that was for my lord, and on waking up I found I was a prisoner in my own treasure-house.' `Prisoner, tell me, who was it that wrought this unbreakable chain?' `It was I,'said the prisoner, `who forged this chain very carefully. I thought my invincible power would hold the world captive leaving me in a freedom undisturbed. Thus night and day I worked at the chain with huge fires and cruel hard strokes. When at last the work was done and the links were complete and unbreakable, I found that it held me in its grip.'
