In addition to the story line, I think the God of Small Things has a lot of good life lessons/morals in it. I found some quotes that I think have a good lesson in them, or apply to life itself, and not just the story line.

On page 272: "And there it was again. Another religion turned against itself. Another edifice constructed by the human mind, decimated by human nature." I find that this applies to one of the human race's biggest struggles, nurture vs. nature.

And on page 271: "It is not in the Party's interests to take up such matters. Individual's interest is subordinate to the organization's interest. Violating Party Discipline means violating Party Unity." This quote reminded me of another book I'm currently reading for European History, Germinal. In Germinal, the mine owners/share holders indirectly force the miners into dangerous working conditions by not paying them enough for timbering, so the workers will only mine for coal. They are only concerned about the money, about the establishment. I think that rings true here as well. They don't care for individual situations, but rather the establishment as a whole.
