From personal experience, I know for sure that the number one thing that saddens the dead more than our grief — is not being conscious of their existence around us. They do want you to talk to them as if they were still in a physical body. They do want you to play their favorite music, keep their pictures out, and continue living as if they never went away. However, time and "corruption" have blurred the lines between the living and the dead, between man and Nature, and between the physical and the etheric. There was a time when man could communicate with animals, plants, the ether, and the dead. To do so requires one to access higher levels of consciousness, and this knowledge has been hidden from us. Why? Because then the plants would tell us how to cure ourselves. The animals would show us their feelings, and the dead would tell us that good acts do matter. In all, we would come to know that we are all one. And most importantly, we would be alerted of threats and opportunities, good and evil, truth vs. fiction. We would have eyes working for humanity from every angle, and this threatens "the corrupt". Secret societies exist to hide these truths, and to make sure lies are preserved from generation to generation.
