In truth, I think this book is somewhere between 4 and 5 stars, but since this site only does full star intervals, I decided to give it 5 stars, since I enjoyed the first seven volumes so much. Frankly, after 2800 pages of build-up, it would be impossible for any ending to feel completely satisfying. But still, this is a pretty solid finish to one of the longest graphic novels ever written.
Vol. 7 feel like the emotional and narrative climax. Vol. 8, "Jetavana," is something of a denouement, devoted to wrapping up major storylines and seeing the characters through to the ends of their lives. Buddha rehabilitates some of his enemies, has a final showdown with Devadatta, leader of a breakaway Buddhist sect, and sets out on his final journey. The deaths of major characters have adequate emotional impact, and Buddha's death in the final pages may produce a tear or two on the reader's part. Once again, the writing is philosophically compelling, the characters are psychologically complex and surprisingly three-dimensional, and the artwork is superb.
One of the interesting elements in Vol. 8 is the way that Osamu Tezuka incorporates the Buddhist concept of karma into the plot. With great irony, the author shows how the heroes and villains produce both good and bad karma - good and bad results - through their actions. The king who feared that his son would commit patricide imprisons his son; that prince grows up to hate his father and later imprisons his father, who starves to death - in short, the king, through his cruelty, makes his worst fears come true. Similarly, the villain Devadatta poisons the same king, thinking that this scheme would get the prince out of prison, remove the need for patricide, and help Devadatta gain the power to overthrow Buddha. This scheme, committed with malice and greed, also backfires: The prince gets out of prison, but opts to kill his father anyway; and Devadatta briefly takes over the Buddhist movement, only to lose power and die pathetically. Overall, these plot lines demonstrate the Buddha's belief that actions done for unjust reasons will ultimately rebound upon individuals. Cruel monarchs and powerhungry zealots ultimately lose everything. The implication here is that, if all of these characters had shown more compassion for each other, if they had loved more, then they would have found peace, even if that didn't mean getting everything they wanted. That is a powerful message, and it accurately captures some of the complexity of Buddhist thought.
So what keeps me from giving this book itself a full 5 stars, separate from how much I enjoyed reading the volume? There are a few notable flaws here. Several supporting characters, who received significant attention in previous volumes, basically disappear from the story, without any real resolution. The author also has a tendency to overplot somewhat. We understand the details of Devadatta's scheme to overthrow Buddha and the king, but Devadatta's motivations remain ambiguous. Does he act purely to advance his own scheme to take over Buddhism, or does he care for the prince? The plot is unclear. Perhaps Osamu Tezuka wanted to leave his main villain something of a cypher. Still, I would have liked the novel to be a bit more spelled out in that regard. There are also some moments - a villain alternating between being a good Buddhist and a vengeful man; Buddha reaming out his relatives - that felt inauthentic to the characters' personalities, as developed so far. Finally, I wished the final pages had portrayed Nirvana in some way. Still, the author hints that Buddha is headed on a journey "to the center of Nature," so the post-death experience is addressed in some form. Since Buddha is shown to be unsure what lies beyond the grave, perhaps the author wanted to leave things a bit unresolved, reflecting the mystery surrounding death.
Overall, despite the flaws I mentioned, this was a satisfying end to a landmark graphic novel that felt more like literature than a youthful comic strip.
