The works of Pérez Galdós tend to be interpreted as an artistic representation of the man and society of his time. In this way, he proceeds with an aesthetic in constant evolution, and from 1889 with the publication of Realidad in the atmosphere of the end of the century in crisis, he seeks a new aesthetic change with sprititual realism or spiritualism, rather than objective and realistic analysis of contemporary realities, it focuses more on the inner human figure and the essence of belief. In Spanish literature, the term spiritualista began to appear in 1887. Whereas in the realist novels the individual figure projected and reflected the image of society, in the spiritualistic novels, a particularly prominent figure among ordinary people described the process of finding an answer to the ultimate task of human life. From Realidad, 'great love' became the subject of his works as a human duty, such as 'compassion', 'love for others', and 'love beyond convention', and Nazarín(1895), Halma(1895), and Misericordia(1897) contain the message that the internalized virtue of Christ can give great meaning to the lives of individuals and groups. In reality Nazarín and Halma are closely related and considered as one novel. The Christian ideal of his savior reveals the meanness, pettiness and falsehoods prevailing in the world in which the savior involves. In these novels Galdós shows up the figure of a savior who Galdós believed could save Spain from a crisis in Nazarín and Halma, both of which are regarded as the real beginnings of Galdos' spiritualist novels.
