You forgot Christianity, Jesus also promises to take you to heaven (= Nirvana) after death so you can avoid rebirth. 

I'm honestly not an expert on religion but reading the Bible after years of dabbling in Buddhism opened some new perspectives. If you are born again of water and spirit (i.e. baptized), you can enter the Kingdom of Heaven, and there appears to be no more rebirth after that.

However, it does seem to be that this very important ritual has been cheapened and degraded almost to complete profanity by contemporary Christendom, where they mostly perform in on babies by sprinkling water on their heads. I have been baptized this way and I did not feel like I was in heaven, so maybe my church just didn't have the right idea.

In the Bible, it's done via full submersion, but to my knowledge, the only remaining church that still does it that way is the Eastern Orthodox one. Also, the Constantine movie with Keanu Reeves had an interesting take on it, with a very dramatic baptism scene as far as I can remember.

Lastly, you could look into Shamanism. Ayahuasca has very powerful healing properties, and will definitely help cleanse you of a ton of accumulated karma if you have the emotional fortitude and the willpower to endure the comeup. Depending on where you are in life you'll probably need multiple sessions, and you should be very careful to pick a shaman that you can trust to guide you through this, as it is NOT an easy experience and definitely not recreational.

Find a Baptist church lol

Not too familiar with all the protestant denominations but as far as I can tell they're all heretics, since they broke off from the Catholic church in an effort to correct their copious heresies.

Hence, they have no apostolic succession and therefore no authorization to baptize in Jesus's name. If baptism can really break the cycle of reincarnation, you don't think a little water and some magic words are enough to accomplish that, do you?
