Grief (novel)
During the course of the novel, the ideas of the stages of grief are introduced. The stages are denial, anger, depression, and acceptance. The narrator, as well as other characters in the story, slowly passes through these stages in trying to deal with death.
Four stages of enlightenment
The second stage is that of the (Sanskrit: ), literally meaning "one who once () comes ()". The once-returner will at most return to the realm of the senses (the lowest being human and the highest being the devas wielding power over the creations of others) one more time. Both the stream-enterer and the once-returner have abandoned the first three fetters. The stream-enterer and once-returner are distinguished by the fact that the once-returner has weakened lust, hate, and delusion to a greater degree. The once-returner therefore has fewer than seven rebirths. Once-returners do not have only one more rebirth, as the name suggests, for that may not even be said with certainty about the non-returner who can take multiple rebirths in the five "Pure Abodes". They do, however, only have one more rebirth in the realm of the senses, excluding, of course, the planes of hell, animals and hungry ghosts.
