whilst belonging is important it is not the most important aspect to a being, it is instead being an individual. not one person in this world is the same as another. it is true that others influence us and that a sense of a belonging has a great impact upon us however, ultimately who we are is what truly matters
It's true that in the final analysis we have to be true to ourselves to be happy and fulfilled. That doesn't mean that there isn't a great value in certain types of "belonging," it just depends on the situation. Do we belong to a certain group because we bend to their collective will, or do we belong because we put someone else's needs ahead of our own. The answers to those questions will tell you if you are engaging in the right kind of of "belonging."
We might find that the rub in this consideration is that we often cannot be our truest selves when we don't have an identity in a group. Whether our group is family or friends, we often need others to see us, to value us, and to let us talk to them in order to flesh out and discover the kind of person we really are inside.
For instance, a person might find that they love to teach. If there is no one around to instruct not only does the realization of this passion become unlikely, it becomes meaningless.
Of course, our spiritual identity is not defined by occupation, but we are beings of many facets that all work together to create our sense of self. Occupation, calling, and socially defined elements of personhood help us define our true self.
i believe that there is a balance to be struck, which is v important-- between being a part of society, 'belonging' to a larger grouip; and being one's own self, an individual. both extremes can be harmful in some ways, no?
