For a great light cannot be called the cause of a single small creation since the latter will never emerge directly from the former... Even though “two hundred include one hundred” and the higher level includes the lower level, the higher level is not called a cause since it is not from there that the effect develops....because the Emanator, blessed be His Name, instituted the law of gradation. As explained above (Opening 30) we cannot say that it was impossible for the Emanator to do otherwise. However, since He wanted gradation, this is what gradation involves.
