To “practice” is to repeat an activity in order to improve one’s skill. When learning a sport, or a language, or how to drive a car, we spend a lot of time at the beginning repeating, or practicing, different actions and exercises. We do this so that when the time comes to do the real thing, our action will be automatic and easy.
Since the purpose of Buddhism is to manage our entire life, we are practicing all the time!
Here are some good sources of information about Buddhist practice:
