Sandskrit basics: Yoga class terms and their meanings

Most yogis have a pretty good knowledge of the Sankrit words for their favourite poses. That's because most yoga teachers (a least I've found) use both the original and western names of the poses. It's a good lesson for people like myself who don't know Sanskrit or much about the history of yoga -- now that I've been going regularly, I know that Adho Mukha Svanasana means downward dog, Tadasana means mountain post and Utthita Trikonasana means extended triangle pose.

Fitsugar has together a short tutorial on Sanskrit in yoga ... you probably won't need to worry about memorizing the names of poses unless you're becoming a teacher, but it can't hurt, right?
