People interested in learning about the death state should also read The Buddhist Book of the Dead. It's fantastic.
Long ago, about the time I first started posting messages on this website, I described an experience in Mexico, that confirmed many of the teachings in the above named book. I'll recount it again. My wife and I went to spend Christmas Eve in her home town of Manalisco, Jalisco during Chriistmas of 1982.
On Christmas Eve, we went to the local church to attend mass. As everyone was leaving the mass, they had to kiss a doll of Baby Jesus in a crib. In no way, did I want to place my mouth over the spittle of a hundred or more other people. I began to complain about having to do this.
When we returned to her cousins' house, they stayed downstairs to talk. I went upstairs to bed, going to sleep immediately. After awhile, I became aware that I had not been breathing for a while. Suddenly, I started seeing all kinds of flashing, colored lights and dark shapes, exactly as described in the Buddhist Book of the Dead. It took me a lot of effort to start breathing again and awaken. Finally, when I woke up, I went downstairs, telling my wife and her cousins what had happened to me. They said "God" was punishing me for having refused to kiss that doll which was all covered with slobber.
I was so afraid to go back to sleep, that I drank a bottle of tequila in order to pass out. My wife remained awake to make sure that I didn't go over "to the other side" again.
It seems that I had come down with a Mexican folk disease called "Susto (Fright)," in which one finds himself partly in this world, partly in the next. For two or three years after that, I had frequent relapses. Then, after that, they never returned. Now that I'm 75 years old, I'm deathly afraid that I'm becoming an excellent candidate for "the last relapse." I don't think I'll be surviving this last one!
