Lately I started to think If reincarnation is real and when someone CTBs then he/she is put to worse place than before
This post got me to thinking.
Reincarnation has roots in Indian traditions. I don't know about Hindis, but Gautama Buddha didn't have a problem with ctb. Rebirth is based on what one clings to, and the fruits of one's actions in the most recent and in past lives/states. There could rebirth in all kinds of realms, like hells, heavens, formless, neither form nor not form, etc., and the fruits lead not only to the realm but the conditions experienced in that realm. Earth is considered one of the better realms, not a heaven but definitely not a hell. And all conditions eventually pass unless one gets completely out of the cycles of suffering and self and attains nirvana, a state of neither existing nor not existing, as Gautama said, bliss, and difficult to explain, even with direct experience. Buddhism has roots in Jainism and other Indian traditions, and are related in some ways to Hinduism, such as Bramahnism.
Abrahamic faiths are the ones who consider actions leading to a final reward or damnation. But as far as I can recall, there is nothing in the Bible that says ctb leads to punishment, that belief comes from the dogmas of the traditions but not the source. I can't speak to the Quran, I haven't studied Islam.
New Age beliefs say that one will have to come back and finish the lessons they skipped out on.
So my personal opinion is that fears about punishment for ctb are cultural. I could argue that all philosophies and religious traditions and their foundational texts are culturally influenced and culturally perpetuated by dominant, controlling power structures. Not all cultures consider ctb a sin or subject to condemnation. Some folks continue to take part in a religious tradition because of the fear that judgment and punishment might be real, so better to engage in what they're not convinced of just in case it's true, and I think that same logic can apply to fearing the consequences of ctb.
If consciousness isn't solely a condition of physical existence, I'll be sure to post here after I ctb what actually happens.
