4👑☸ Cattāri Ariya-saccaṃ 四聖諦
karma and rebirth ♾️👶
kamma = action, work, deed
karma = sanskrit spelling for kamma.
Rebirth♾️👶, Reincarnation
Jāti = birth, but there really isn't a standard word or phrase used everywhere in the EBT. Similar to how nirvana has many words and phrases to describe the same phenomena.
Let's clear up this wrong view right away
Among modern skeptical Buddhists who don't believe or like the concept of rebirth, they use a number of ways to misrepresent the EBT. Such as, "The Buddha didn't believe rebirth, he simply accepted the cultural beliefs of his time."
Actually, it's true the Buddha didn't believe in rebirth
He didn't believe it. He knew it to be true through direct experience (see 6ab recollection of past lives, divine eye, and te-vijja (three vedas)). This is something all of the arahants, not just the Buddha, with strong samadhi witnessed for themselves. In fact it doesn't even require an arahant or even a stream enterer, or even belief in Buddhism. All it takes is strong samadhi. Plenty of yogis, past and present, Taoist, Hindu, Essene, Christian mystics, atheists, have witnessed this phenomena for themselves. It's fine if you think they're just hallucinating, but understand they're not professing belief, they're affirming that rebirth is a natural phenomena directly observable to anyone with strong enough samadhi, in the same way you don't believe in gravity, you directly experience its effects and you know it to be true.
Don't be surprised if they look at you funny
If you're skeptical about rebirth, that's totally fine. But if you want to know exactly how the Buddha regarded rebirth and karma, you should do your homework and study the EBT rather than grasping at false views and misrepresentation of EBT that supports your bias. Rebirth is so embedded throughout the suttas, you could almost open page at random and encounter it within a few pages.
