is true because this life (and this planet) is a university for get a awesome degree: clean our karmatic soul, i mean they (the celestial tribunal: angels and wisdom beings for all the religous /good people - saints - martirs - that coexist in heaven) give each soul an amazing oportunity for re-star each time that we reborn, for clean the past mistakes and sins cause when a person do a bad thing that person make a damage that needs to be fixed for equalize and balance the universe, so the karma its just that, you receve it what you do (in past - lifes) so you reborn for that, survive here and try to being a better person, with goodness, compassion, mercy, for others, and that kind of stuffs was cleaning the soul (btw, the soul its the most important treasure and the most precious jewel that we have) and we can rise into heaven or a celestial dimensional ascendent space when we are purify 100% but for make that we have to reborn multiples times, each return could help us to clean or not. but the most "clean" soul people like saints, or the ppl that die for others, they win the enter to heavens (all the heaven: isnt difference between catholic or another ones. its like the same, peace, infinite love and peacefull place with love and good vibes) but each soul have to win that entrance with of course good vibes, but if a person not enter ther its ok, they give to us a lot of new reborns for make it. Someday a person dont return here anymore cause finnaly enter into that superior place :) everybody can enter but isnt sooo easy, isnt a religious thing, its more about soul, the good intentions, being like a saint person for help others always, without extreme sins and of course try to focus in being a better person. but everyone can enter inside that with the soul purify. and is the travel here try to purify us and helping otheres to the same :)
