Very interesting stuff indeed, i saw this a few days ago actually..
One thing i like about Tibetan Buddhism is that it explains there may be Negative and positive experiences when you die. It makes perfect sense right? Why the fuck would death be sunshine and lollypops right away. It doesnt mean your in hell if there are scary aspects to death.
The bright light they talk about is interesting. Ive heard from people in my real life who saw this light. They say it was the most intense and beautiful thing ever
