The last line of this section refers to "nature without check with original energy." If you are familiar with other American poets of the nineteenth century, you may recognize this trend toward a belief in nature as having its own independence of spirit which should be trusted above all else—an innateness, and an intuitiveness, which should be relied upon, throwing aside the tendency to overthink and overcomplicate things. Ralph Waldo Emerson was also of this school of thought, which is usually called transcendentalism. The idea is that the trappings of "creeds" should be thrown aside because they make it difficult for people to connect with the world around them as nature intended. Emerson's essay "Self-Reliance" focuses upon this concept and the idea that all people have in themselves the same instincts as other creatures in nature but that too much schooling has made them unable or unwilling to rely upon these instincts.
