I don’t believe in eternal paradise. Rather, I don’t think it is possible. Eternity takes precedent over judgement. Eternity is above choice. By definition, whatever is eternal will include everything, ever. What guarantee do I have that after an eternity of years, I wouldn’t get bored of paradise? Or that the being offering it would die, or get deposed? Oblivion is the only option I would ever choose
As is everything with Hindus, it’s way more complicated than that. Fun fact: Siddarth Gautauma, the Buddha, was totally a Hindu prince. And now there’s very very few Buddhists in India and lots of other cultures have grabbed him and run with it. 
The way I read it, eternal paradise is the best thing I could ever imagine. So, any other choice is redundant. Why limit myself to only reincarnation or Nirvana when I can have it all?
Yeah, I’ve read up a little on Siddarth in the past and knew that Buddhism broke off from Hinduism, which is why both share a belief in reincarnation and both have a similar “reward” at the end.
