Padmasambhava

From the Tibetan Book of the Dead, they are told to use a guru or a disciple of a guru, or a Dharma-brother, to help them focus on their own enlightenment and perceive their own consciousness. They are supposed to help them keep their thoughts from straying back to the present world and all the things they will be leaving behind. They believe that the mind is more than just emptiness after death; it is a great luminosity that goes forth. I see the luminosity as a spirit or soul going towards another life, or “heaven” as most people will call it.
The Book of the Great Liberation tells us that we are all one and we are inseparable. It keeps telling us that until we are able to grasp that idea, we will not be able to reach enlightenment. The Book says the mind is the unity of all things, yet not composed of them. It says the mind is without beginning or end and has been shining forever, like the sun. It says the ultimate goal is to understand your mind.
I think our “light,” or I like to think “spirit” or “soul,” will always “shine on” so to speak. I agree with the ideas from the Tibetan Book of the Dead and the Book of the Great Liberation, that our light has always been there and will always live on.
