If your instrument or tool is rusted, even if it might be your own,
no matter how ideally you set your mind and thoughts,
you cannot properly do the work you want with that instrument or tool.
In the same way, if the tool of your brain is hardened and ill-formed,
you cannot do things as you want no matter how much you set your mind,
think positively and take action.
That is why I tell you to fix your brain.
