Buddhism and Hinduism Parallels

Hi,

I found the movie viewing pretty interesting, and now have a lot of questions about it. But, in regards to the influence of Vedic beliefs on Buddhism, I think there are definitely some parallels that can be drawn between the two beliefs. And, I can understand why in some places society was strongly based around Hinduism (and the Vedic traditions), yet also how it became much less popular, with the new influx of Buddhism. Both belief systems rely on the idea that everyone suffers in their life. In Hinduism, someone suffers if they are in one of the lower classes, and those that are placed into the higher classes meant that they had suffered in past lives and were just closer to the Ultimate Goal: Nirvana. In Buddhism, Siddhartha agrees with his people, and says that everyone suffers, no matter the person, no matter the class. People will eventually and inevitably feel some loss, suffering, and/or illness. His philosophy is, instead of waiting for your next life to hopefully be better, humans need to look at their situations with more positivity, and hope. Under his guidance, his people can find a life of true bliss, and awareness. I personally think that as these two belief systems began to intermix with each other, Buddhism became popular very fast because you didn't have to wait as long to find happiness. The idea that one can change their fate as they live, and are not stuck in a caste because they were born into it, and therefore deserve to suffer, became much more desirable. Yet both beliefs have the same undertone that everyone is suffering, and working toward a better life (which, may or may not have had an influence in the creations of Buddhism, and may be why there are even similar parallels, since the Vedic ideas were around for a while before Buddhism).
