"Presumably there are energies, to which each human is sensitive, that we cannot yet detect by means of our instruments. Built into our brains and our bodies are very sensitive tuneable receivers for energies that we do not yet know about in our science but that each one of us can detect under the proper circumstances and the proper state of mind. We can tune our nervous systems and bodies to receive these energies. We can also tune our brains and bodies to transmit these energies."

-- John C. Lilly
