We might have not born to carry out acts and pass away just like the other ‘beings’ as the intellectuality part of ours draws a line. In one of the well-known religions, it is indicated, according to Garuda Puranam (considered to be one of the holy relics), that one would be judged, in their afterlife, upon those acts that they had committed on the earth, whether they should either go to heaven or hell.
However, the relic mentioned that in order to be judged by Yamadharma Raj (lord of death; King of Naraka) they would need to cross the river, Vaitarni Nadi (a river that lies between the Earth and Naraka or, the court of judgement). When my grandmother passed away, they performed rituals for 11 days following her demise. Both my father and his sibling performed some rituals stated by the religion. They were asked to offer slippers and umbrella and by performing this act, it would assist her in leading her way, comfortably, to Naraka for judgement.
However, it was noticed that those things were taken, by those priests who performed those rituals, latter. It can be presumed as a witty remark as it was the same community that coined the term: Karma. Karma is said those acts resulting from one’s actions; it usually occurs, according to not only the most two prominent religions, Hinduism, and Buddhism, but also by many who believe in, on the land we breathe and express emotions. If Karma had already been doing its part, don’t you think it is unfair to judge after death despite being getting back everything (on the earth) for our acts? If it had had gotten the same way back how one would have dealt with or treated people -punished for those sins, and given privileges for good acts that one had committed- why would one have to ‘again’, all the way, go through punishments or privileges decided by that judgemental place, Naraka?
Maybe, it might be the fact that the aforementioned holy relic had been written to not only limit people from wrongdoings but also to (insist to) perform good acts. In addition, those acts, are only considered (for Karma) if they are being committed through a physical channel yet, limiting to that of committing through mind or inner voice. Nightmares might not be considered for the acts that we commit in our minds or inner voices.
