You cannot express or experience what is not true. Mind does all the expressing there is and experiences itself as total perfection all the time. To oneself, the human seems to be substance, but one’s sense of substance involves error because it claims to emanate from outside the focal distance of infinity. (See S&H 301:23-29)
You do not exchange one picture of material foundation for another. You live as the self-supporting, self-sustaining, complete infinite, and are not helped or hindered by ‘another’ in any form.
