That right there has always interested me, for the fact that jeets version of "Heaven" is just the Christian concept of the Pit, or the second "Hell". There's technically two destinations for the damned Biblically. there's the Hell that exists right now on this side of the throne of judgement, that's the one everybody thinks of, fire, brimstone, gnashing of teeth and smoke, etc. That Hell is just a waiting room for Judgement day. To which after judgment day, Hell is emptied out and the damned and Satan are thrown into what's called the eternal pit. Quite the opposite of traditional fires of Hell.
A cold dark place entirely separated from God and his peace, separated from creation itself. It's a Dark place where you, as just a consciousness, eternally grapple with your sin and the mistakes of your life. Floating in a dark void consisting purely of the sins committed by humanity. A cosmic dustbin for all the pains and sins and horrors of this lifetime, to be sealed away and never opened again. that is the eternal pit and ultimately, it's what the Hindus want as the end stage of their religion. To stop being reincarnated and to be thrown into the Eternal pit, only to call it Nirvana.
TL DR - Hinduism is a death cult engineered to take it's worshippers straight to hell, without remorse. Because they call it Nirvana, or Heaven in hindu-babble.
