Peacock in Buddhism

http://www.chinabuddhismencyclopedia.com/en/index.php?title=Peacock

Peacocks are said to have the ability of eating poisonous plants without being affected by them. Because of that, they are synonymous with the great Bodhisattvas. A Bodhisattva is able to take delusions as the path toward Liberation and transform the poisonousMind of Ignorance, desire and hatred [ moha, raga, dvesa ] into the Thought of Enlightenment or Bodhicitta, which opens colourfully like the peacocks' tail.
