Like the title says, I'm curious about the School you follow, why so, and I wonder if you've looked into others. Also what your religious upbringing may have been.
I'm certain this has been discussed before, but this will identify active members better to other active members.
My own upbringing is sporadic doses of protestant Christianity, Pentecostal at times. After adulthood I ran the gamut; atheist at times, seminarian at others. It was while listening to the Bible on CD that I suddenly, simply could not bring myself to believe it. Within two months I had lost my mother AND my savior god. I took a pretty good tailspin from there, to the point where I was obsessing so badly that I couldn't function. Couldn't eat. Couldn't sleep. Couldn't work. I was convinced that I was witnessing my own descent into insanity. In desperation I set up a candle in a dark background, and sat and stared at that candle. I, like many others, thought that meditation meant to stop thinking. Well, that didn't happen, but at the end of the three to five minutes that seemed an eternity I did feel better. So I did it a few more times. I also erroneously thought that the Buddha invented meditation, so I determined to look into Buddhism.
(For those of other schools, please don't take offense, nothing I'm about to say is intended as an insult. I firmly believe that a) your school chooses you, or b) you were happy with your first school and saw no reason to look elsewhere.)
The first Temple I found was a Won Buddhist Temple (a semi-obscure sect of Korean Buddhism). To this day it's my favorite temple and probably the nicest people. But the doctrine didn't reference the Buddha, or even depict him. I then looked into Zen for awhile, but it left me cold for some reason. I moved to Tibetan Vajrayana but the focus on rirual reminded me too much of Catholicism. In the end I looked online. I discovered two quizzes under 'which school of Buddhism is right for me'. Both came up with Zen, or Thai Forest Theravada. Well, Zen was out (although I did try again), so I looked into Theravada and appreciated it's focus on the Early Buddhist Texts and meditation. Yes it has it's flaws, but much like Islam, it's main flaws seem to be more cultural than doctrinal (although the doctrines are flawed as well).
To be frank, my departure from Buddhism as a whole is the chanting. I understand it's function, but I take issue with chanting things I don't believe (some of the supernatural aspects) in a language I don't understand.
Anyway, that's my story...
