What's the deal with your nickname? How did you get it? If your nickname is self-explanatory, then tell everyone when you first started using the internet, and what was the first thing that made you say "wow, this isn't just a place for freaks after all?" Was it a website? Was it an email from a long-lost friend? Go on, spill it.
Samsara is a buddist word used to describe the continual cycle of birth, growth, decline, death, and rebirth. I picked the nickname back in highschool after seeing it in a Webster's dictionary and have used it since.
Despite the strong spiritual ties to the word, there is also the physical. We are all made of recycled parts. Many of the molecular particles of our ancestors may very well end up in today's cereal (or whatever the FDA allows these days).
