"Is it wrong/selfish to want abundance in this physical world in the form of money for an easier and better living situation? If yes, okay. If no, then how do we go about getting this abundance? If we ask but at the same time feel as if we should not be asking because we think it might be selfish, how do we eliminate this feeling of not worthiness?"
"Know, my child, that whatever you desire, I desire. Whatever dreams, hopes and wishes you have for yourself, I have for you as well. I want for you to be happy and joyful. I do understand that the physical plane on which you reside has a need for monetary compensation or energy exchanges as of now. So to answer your question more directly: There is nothing wrong with wanting to have financial abundance. Know that there is no lack of any kind in my perfect universe. When you take, you do not take away the opportunity for another to receive! I am infinite and so are you. Whatever I create is infinite. Whatever you create has the potential to be infinite as well if you so desire.
