How does gathering Empaths help to raise the love vibration?

When we first began meeting with the Guardians of Light, the first thing they asked us to do was to gather the Children of Light and create a community of support for them. Our guides from Aldebaran explained:

“Empaths are the true stewards of the Earth, and if they are united as one force, they have the ability to triumph over darkness. Empathy and love cures all ills and all isms, and this alone will help humanity evolve. By supporting Empaths and gathering them together, it will automatically raise the love vibration on the planet. With a grid of Lighthouses around the globe, Empaths can work with their gifts in unison through metaphysical alchemy to transmute negative frequencies, allowing empathy to return to the planet as it once was in the days of Lemuria and Atlantis.”
