The human mind's almost habitual mode of reasoning takes for granted that we have an internal mental world and look out upon an external physical world. The human mind assumes that our consciousness is in our body, not the other way about—that the fleshly body is actually in human consciousness.
In her works, Mary Baker Eddy, the Discoverer and Founder of Christian Science, makes clear that the body is embraced in thought. But while not compromising the statement of truth on this subject, her touch is gentle, not aggressively urging on the reader more than he or she can deal with. She is lovingly willing to stand where, perhaps, the reader is standing, and to help him move on from there, toward more spiritual concepts.
Because our body, and entire experience, are actually within thought, if we never mentally entertained anything vital, lively, vigorous, then it's likely that nothing too lively would surface in our experience. But the opposite holds true too. Divine Life-impelled thinking—intelligent, Spirit-filled consciousness that expresses the one Mind—enriches, enlivens, heals, and directs our experience. Such consciousness can cause our life to fan out in new, progressive directions. To the degree that we accept the fact that the divine Mind is the only Mind of man, we make better judgments, take more benevolent actions, enjoy steadier health and healing.
