I analyzed aspects of diaspora and alterity in Bumsin Park`s novel, Namaste, from two standpoints. The one is alterity rooted in conceptual difference, and the other is alterity in nunbuchoe(Buddha-in-eye)-difference. The conceptual difference is returned to identity finally. Nunbuchoe (Buddha-in-eye)-difference is not returned to identity. This difference is an absolute and ultimate difference, and it can be reached by sensibility and transcendental experience. It makes him to throw away his identity and to reveal self as the other. In the reason of the difference in Buddha-in-eye, the distinction between this and that falls apart, the power, the discourse of exclusion and the violence which held inside of it loose their strength gradually. In the light of alterity in conceptual difference, this novel is a good work. Park, having multi-culturalism and buddhist world-view, not only described objectively the miserable reality of migrant laborers in Korea but also presented a tragic vision. However, he could not reach to the alterity in nunbuchoe-difference, and regarded migrant laborers as the object of mercy. It is the othering of migrant laborers. Park represented hero, Kamil as a very highly good man. Even though Korean break his leg and cut off his finger, Kamil do not hate and blame Korean. Kamil is not a subject as a subaltern but a good other represented by writer. That is the violence of representation. Such writer`s views are in accord with Korean bourgeois`s ideology that they should respect difference as long as migrant laborers are a good other. This work substitutes ethnic contradiction for class contradiction in capitalist society. Existentialist sufferings and various wrinkles and folds of life in contradictory reality are simplified to ethnic problem. Finally, this work solves problems to return to the mythic world, Kailas. The writer, without a keen recognition and confrontation for irrationality of world, looks migrant laborer in the view of conceptual difference and Korean bourgeois ideology. I suggest that the novel about migrant worker should create a character and narrative, and the world of work from the paradigm of the alterity in nunbuchoe-difference.
