Naga Tree

naga tree When Maitreya as King of the Mountain killed Rudra (as Hayagriva): As he said this, his bowels loosened involuntarily and the excrement fell into the ocean and so was purified, and there at once sprang up a precious sandalwood tree [believed to preserve] which was a Wish-granting tree. This tree took root in the nether world of the nagas, spread its foliage in the realm of the ashuras, and bore its fruit in the realm of the gods. And the fruits were named amrita (elixir of immortality). http://www.khandro.net/deity_tale_of_two.htm cf. Yggdrasil
