The mandala (tib. Kyilokor) is a geometrical design
      used for the aid of visualization during meditations.  There are a wide variety of
      mandalas ranging from those that represent the history of time, to those that offer
      tantric designs for the aid of visualizations.  Having a circle as the main theme,
      the mandala incorporates many shapes and colors each with specific significance for the
      practitioner's advancement along the path towards nirvana.  
      This mandala has a vadjra (dorje) as its central
      theme.  The vadjra is depicted in the center, as the symbol of emptiness and power.
        Surrounding the vadjra are the eight auspicious symbols of Tibetan Buddhism: the
      wheel of the Dharma, the right turning conch shell, the parasol, the endless knot, the
      victory sign, the vase, the golden fish, and the lotus blossom.  Found within the
      geometric design are small creatures charged with duty of being Dharmapalas, or Dharma
      protectors.
