NUMEROUS statements concerning what is termed the world can be found in the Bible and in the writings of Mary Baker Eddy. Many of these statements refer to the unreal and temporary universe, in which mortals think they dwell. Christian Science teaches that the temporary state of existence is but the supposititious outgrowth of mankind's belief in the evidence of the material senses.
Explaining this vital point in "Science and Health with Key to the Scriptures," Mrs. Eddy writes (p.86): "Mortal mind sees what it believes as certainly as it believes what it sees. It feels, hears, and sees its own thoughts." She further develops this subject in her reply to the following question in "Unity of Good" (p.8): "Is anything real of which the physical senses are cognizant?" She writes in part: "Everything is as real as you make it, and no more so. What you see, hear, feel, is a mode of consciousness, and can have no other reality than the sense you entertain of it." In the next paragraph she adds, "It is dangerous to rest upon the evidence of the senses, for this evidence is not absolute, and therefore not real, in our sense of the word."
Through Science we learn that every mortal lives in a world of his own thoughts. What he thinks that he feels, hears, and sees constitutes the phenomena of his present world.
