"No money will be necessary because we will be exchanging our contributions (or gifts) for another’s contributions and all our needs will then be met.
This community living may sound very serious, but actually, it is not. Our passions and contributions come naturally to us, we can take them lightly and not so seriously, but still be dedicated and sincere. The remainder of the time we can spend having fun with our brothers and sisters, communing with nature, and being present in our sanctuaries of community."
