Three things have kept me from posting recently.
One is studying for the Cisco Certified Entry Level Network Technician test. I did pass it. The test was fairly tame compared to the grueling preparation, but that's what grueling preparation is for.
One is a death in the family. Fortunately, not mine.
And the other is Ingress, which is a game that deals with energy fields and exotic matter. It is currently in closed beta, but if you have an Android smartphone, you can request an invitation at www.ingress.com.
I mention this here because of the overlap in my own interests between the subject of resonances of healing crystals and vital energies and the themes of the Ingress game.
