@dharma bum,
I think that if the world we see is mind, it is the universal subjective mind that we see. When I say this I mean that what we see is a manefestation of the consciousness of all the minds of sentient kind. Since it is all the minds of sentient kind, our inabilty to change it comes from the presence of other ego consciousnesses of sentient kind.
Now when a man sees a door closing in reality, it is a result of the singular objective mind interacting with the univeral subjective mind. And when this man you are speaking of is sensing what he is sensing it is his objective mind in by it self.
Their is another why that one can look at the subjective and objective mind. One can look at it in terms of consicous (objective) and unconscious (subjective). Now since in most schools of psychological thought the consicous mind is a manefestation of the unconsicous mind. One could argue that he is indeed changing reality in the subjective sense. Also if enough people were to think about the door closing it would close.
I feel that this is
A proper way to look at the dharma. Considering that we are all manefestations of buddha nature, all is enlightenment and all is buddha (If you're hindu replace that with brahaman) and all is mind buddha (brahaman) would be the subjective mind. I would also like to note that subjective mind is one of the definitions of god in websters.
I would also like to note that in frudiean psychology the conscious mind is made by the unconscious to fullfill the unconsciouses needs and desires. Similar to the religious view that god created us for his glory and purpose.
Thanks
Peace & love
