The exchange of energy is the only thing that is real. The material world is an illusion. Love is the most precious commodity—it is the energy with the highest value. But it is not something to be hoarding; it is something to be given away as often and as much as possible. To the degree we give it away, it grows. Preston Smiles, from The Love Mob, joins Barnet and Freeman for an inspiring look at exchanging love to build a reliable community with an evolved system of exchange.
