Amituofo,
Dear Thao
Regarding the meditaiton in Pure Land practice, there is significant meditation practice. However, it varies according to temple and home practice. Meditation is the same as all the traditions, sitting style and then walking and then sitting again. During the services there is a morning kneeling meditation before service begins in some temples like my tonsure temple. And then during the services there are meditations in parts of the service. Pure land meditaiton is reciting the Buddha Amitabha's name or Sakyamuni Buddha's name; bowing meditation, recitation with bowning meditation; caligraphy or other arts meditation to name a few.
