Tibetan Buddhism has such a unifying symbol, known variously as a Refuge assembly, Field of Merit, or Refuge Tree. It is known as a Refuge assembly because it is a visualized gathering of figures representing the three Refuges. It is known as a Field of Merit because by visualizing a great array of Enlightened figures and then making offerings to them, and by performing other skillful actions, such as committing oneself to the Bodhisattva path .
