老栗樹開曇花

公應各僧伽及檀越。請講楞嚴經。昇座說法際。庭前老栗樹。忽湧開優缽曇華數十朵。大如盆。形如芙蕖。色如黃金。含香吐蕊。中空體潔。盛開數月。而不萎謝。見者皆稱奇異。嘆未曾有。

宣化偈曰：

老樹通靈獻妙供。稚童仰首望仙華。
僧伽咸說奇華瑞。檀越皈敬勝菩提。

Witnessing Udumbara flowers bloom on the old chestnut tree

The Master responded to an invitation by various members of the Sangha and benefactors to explain the Shurangama Sutra. When the Master had ascended his seat and was speaking the Dharma, the old chestnut tree in front of the hall suddenly blossomed, sending forth several tens of clusters of Udumbara flowers. They were big as basins and had the form of peonies, with a golden-yellow hue. Rare fragrance exuded from them; and they were empty in the middle, reflecting their purity of form. They bloomed lushly for several months and did not wither. Everyone who saw them pronounced it a marvel and exclaimed that there had never been anything like it before.

The gatha says:
A little magic by the old tree brought forth miraculous offerings,
As the youngsters turned their heads to gaze at the supernatural blooms.
All the Sanghans together agreed on the flowers' propitious rarity,
While respectful donors took refuge with sublime Bodhi
