after a thousand years pass , it builds its own funeral pyre , lining it with cinnamon , myrrh and cassia.climbing to a rest on the very top , it examines the world all throughout the night with the ability to see true good and evil.when the sun rises the next morning , with great sorrow for all that it sees , it sings a haunting song.as it sings , the heat of the sun ignites the expensive spices and the phoenix dies in the flames .
