I would think the 2 are can set your ideas your alight, but what are you going to kindle it with?
the mind is indeed a vessel of knowledge and is a source of actions ,kindled by our knowledge to speak .because without knowledge there is no fire ,no will or direction to do or perform.
speaking from a writer's perspective i cannot create a story magically out of thin air .i have to depend on my many hours of gathering relative knowledge and my memory to transform into a tale of my own .i am sure this is applicable to every other aspects of our lives such as decision making and innovation
you can't kindle a fire without wood or oil ,you can't kindle a mind without stored knowledge.
