So I was thinking, Lets say for example, Somebody believes in karma. They think of the bad things they have done, they start to focus on the bad things that happen to them and attribute it to having bad karma because of whatever they did. Then they might either start trying to live a certain way to avoid "bad karma" or become obsessive about it and constantly live their life in a way which they normally would not, Would it become like a penance maybe? Sort of like "oh I got attacked in the street, That's what I get for..."
What about religion? People might live a certain way to avoid afterlife consequences or in order to gain entry to "heaven" etc.
I'm not specifically relating to karma or religion, It just seemed like a good example of the point i was trying to make. You could attribute this to believing in anything.
Do you think people's life's are put on a different course because of believing in something?
Would you be a different person if you believed in different things? The things you think are obvious, The things you could not imagine living without thinking they were right, or true.
