Create organizations where individuals are free & united.
Free - meaning that they are not bound to an organization where they must follow the rules, or ask for permission, where they are exploited or treated unfairly. Free - also means that they act in full accordance with themselves, and as such - they are free from societal norms.
United - means that they treat all other human beings as Earthians first and foremost - and look for commonalities that can be used to achieve human unity.
Our purpose is like the ‘north star’. It is the guiding principle, to which you can always come back. Unlike a ‘mission’ - it can never be fully achieved.
The purpose could be explained slightly differently:
All Earthians strive towards global unity, keeping in mind that everyone has a right to be free; but only so free so as to not take away another Earthian's freedom.
