Answer:
There are many specific practices, like saying mantras, meditating, doing prostrations, being charitable, making offerings and the like, but generally a Buddhist practitioner will see his or her entire life as being a practice; a part of the path, or Dharma. A Buddhist who does any activity with the earnest intention of benefiting all sentient beings is practicing the Dharma. Even while walking down the street, if one is thinking 'who is the "I" who is walking down the street? Is it my legs doing the walking? Is it my head, thinking about it? What is this thing I call "self"?' one is practicing the Dharma.
