There are a lot of different between both important things.
Moreover, they seem, sometimes, contradictory.
E.g.: I think I can't do it (as a result of thought), but I want to do that (as a result of belief) even I don't have capability.
But today I realise that there is commonality between them, none in the world can change your mind or heart. Myself is the only one that entitle to change them.
Maybe I can't change your heart and so you can't change my mind not to do it...
Mind and Heart, should do they working together as a partner or as a control balance for the other?
