It's true, there are different schools of Buddhism with different emphasis. At the end of the day, Buddhism is Buddhism. Zen is a type of Buddhism, a way of doing Buddhism. Tradition says there are 84,000 different "doors" or entryways to practice. What does that mean? Practically, it means that since we're all confused in our own unique way, there's a path that is appropriate for anyone, regardless of their situation.
One of the best ways to get a feel for what the different traditions are like is to show up at a variety of different centers or temples in your area, if you can. It also helps to read around at a site like DharmaWheel, or to just ask a lot of questions.
I hope that helps a little.
Thanks to the help of generous sponsors (most of them from DharmaWheel), I'm doing a Vajra Armor (Dorje Kotrab) self-retreat this summer. May the merit be yours!
