You’re belief makes you susceptible to the actions of life, things like tragedy, grief, terror and much more!
But also to things like love, joy, and happiness.
Cause if you notice, there are people without any emotions (It’s arguable but shhhhh ), but its hard to find people with just one kind of emotion, be it negative or positive, much less credible.
You cannot have one thing because you have to have the other to distinguish. (in the case of emotions, good, bad and other things)
