The people we share it with can be our friends, lovers, enemies, whatever we deem worthy, whatever we choose. Only someone to share all of our being with. Every religion has a way to solve the problem of how to share ones path. Marriage, soul searching, many others that keep us together for all times. Everyone needs someone to share it with, but it is not so easy to assume that there are ones to share it with for everyone.
Some people never do find someone.
These people follow three different, but in the end, very similar journeys. The weakest of these people go mad. They simply lose their minds. But then these people are no longer people, for what is a person but logical thoughts and emotion. To lose thought is to lose being, because if one cannot realize that they are, then they are not.
