In The Good Earth, discuss the theme of connectedness to the land. Wang words “Land is one’s flesh and blood.” introduce the main theme of the novel. Wang Lung, the central character of the novel, feels a deep respect for the earth.  His house is made of earth and even his gods before whom he places incense are also made of earth. Thus he gains his food, his shelter, and his religion from the earth. As Pearl Buck notes, everything comes out of the earth, but ultimately everything returns to the earth.
