Everyone has his or her own mind that's for sure but the mind is being controlled by we humans, I mean to say everyone controls his or her mind, although there are some times when the mind goes astray and keep wondering on its own you know what I mean, of course having a negative mind will definitely bring negative energy and value why you positive mind will be vice versa, but in all this I think our minds can be controlled by us because whatever we choose to think it worked with think and whatever we choose not to .
