And nothing written here is based on any fact ,just random thoughts that I think when I able to think.
So, have you heard of karma, what do you think is it?
In India there is a term which is very popular among people is Dharma . Dharma is the good deeds we do for eg, philothropy, helping others, etc. It is said that the we should live a life of Dharma and do lot of Dharma so that we can have a better after life( like either we born again in comfortable situation , get heaven, or our soul get peace ).
And the opposite of dharma is Paap(aka sins) which means hurting others physically , emotionally , hurting animals without any reason etc.
Every time people do things , some times they cause Paap unknowingly so it is advised that doing Dharma will help our soul to get rid of all the Paap. If you understood these terms now we can talk about , bathing in holy river Ganga( the water of the river is considered pure and it can never get contaminated) washes all your sins or Paap.
Now you will be wondering where is Karma. The term Karma literally means work nothing else and the philosophy behind it is if you do good karma (that is Dharma) you get good life or after life. And if you do bad karma ( that is Paap) you get bad life or afterlife.
