Conscious death is when you are dying and still your mind at the high level of consciousness. The beautiful example of this when Socrates was given a poison as a death sentence.
And the day he was given poison is one of the most significant days in the history of mankind. His disciples were sitting around him and he was lying down.
He told his disciples, ”I will tell you what is happening. As long as I can, I will go on informing you.”
Then he said, ”Up to my knees, my legs are dead. Please, somebody, pinch my legs so I can know whether I can feel it or not.” Somebody pinched his legs. He said, ”I cannot feel it; the legs have
died. But remember one thing: I am as alive as I ever was. The death of the legs has not cut a part of my life; my life is as whole as it ever was.” Then all of the legs became dead, half of the body. And
he said, ”Half of my body is dead, but I am whole, as whole as ever.”
Then his hands became dead and he said, ”I am still here and I am still whole. Perhaps now my heart will stop, but I can say to you that even though I may not be able to inform you, I will remain,
because if all these parts are gone and I am whole, then it doesn’t matter: the heart is only a part.”
And when he died his face was so delighted, so joyous, that Plato, his disciple, remembers, ”We have never seen his face so full of light, so radiant. Perhaps the last moment when the soul is leaving the body is just like the sunset when the sun is going down and the whole sky becomes so beautiful and radiant.
