The same phenomenon was noted several years ago in Seoul, Korea, where miniature flowers suddenly sprouted from the forehead of a statue of Buddha, and again in 2004, when they were found growing near a Korean government office building.
The photos accompanying these stories document what appear to be miniscule white buds suspended on threadlike stalks. Trouble is, they don't match any known species of plant life, while bearing an exact resemblance to the eggs of an insect known as the lacewing. Lacewing larvae are cannibalistic, so females lay their eggs at the end of filaments the size of human hairs, keeping them out of reach of one another when they hatch. Strange but true.
And what of the Udumbara flower, which we are told only blossoms once every three millennia? It is a myth, a metaphor in Buddhist scripture for how rare it is to encounter a Buddha in the flesh. From the Lotus Sutra:
"The Buddhas are as difficult to meet as the Udumbara flower. It is also as difficult as it would be for a one-eyed tortoise to meet with a hole in a floating log. But our blessings from former lives are deep and thick, and so in this life we have encountered the Buddhadharma. Therefore, Father and Mother, hear us and allow us to leave the home-life. Why? The Buddhas are difficult to get to meet, and such a time is hard to encounter."(Thanks to Rick Elsey for the tip on lacewings.)
