Reincarnation is a major red pill. Every time I learn and study reincarnation beliefs it just makes more and more sense to me, sometimes to the point of bringing me to tears. It provides an explanation for absolutely everything in life - the families we were born into, the people we love and hate, the tragedies we experience, everything.
quick run down:
>we are spiritual beings
>we incarnate on earth to learn lessons so our soul can progress
>we choose our life circumstances to match the lessons we need to learn and the experiences we must go through
>our families, friends and lovers are a 'soul family', who help us at at soul level by interacting with us throughout our material lives
>lower developed souls keep reincarnating in lives where they don't live consciously or progress
>some higher developed souls come to earth to help the rest of us
There has been documented evidence of souls reincarnating, reincarnation was a part of the Bible until it was taken out, and it's a system congruent with every (un-cucked) religion or religious set of beliefs. Things like homosexuality and love-on-first-sight can be explained by samskaras, things we take with us from life to life.
One life time is not enough to learn all a soul needs to learn, that is obvious. Everything that happens to us, even if we first perceive it as unfair, can be explained by past lives.
