In English
It is like going to a goldsmith with a piece of gold and asking him to make some jewelry of the design of your liking. Your business is only to leave the gold with him with the condition that the weight and design should be to your specification. You have no business interfering in the manner in which he converts your lump of gold into the piece of jewel you want. If you start stipulating that he should not burn it in fire, or beat it with a hammer, how can you get the ornament that you ordered?
