又終南庫谷內西南。又名胡盧谷。昔有人於山採斫。遇見一寺。并石室石門。門內並寶器重大不可勝。然不見僧人。是眾僧供用具度。其人裴回顧眄記誌處所。以所齎瓠盧掛於室樹。下山召村人往尋其谷內。樹上往往悉是瓠盧。莫知蹤跡。今有尋山。云石門扇在山崖傍。半入山下。其半雖出無人力開之。今其谷名庫。地名天藏。故谷口府坊皆名天藏。測其山中則彌勒下生方現於俗耳。

Furthermore, in the southwest of Ku (Treasury) Valley in Zhongnan, also named Hulu (Gourd) Valley: in the past, someone was chopping and collecting wood in the mountains when he came upon a temple, along with a stone chamber and a stone door. Inside the door were precious vessels, so heavy they could not be lifted; however, no monks were seen. These were the utensils and implements for the assembly of monks. The man paced back and forth, looking around to mark the location, and hung the bottle gourd he was carrying on a tree by the chamber. Going down the mountain, he summoned villagers to go look for it, but in the valley, gourds hung all over the trees everywhere, and no trace could be found. Now there are those who search the mountain and say that a stone door leaf stands beside a mountain cliff, half-sunk beneath the mountain; although the other half is exposed, human strength cannot open it. Now its valley is named Ku (Treasury) and the place is named Tianzang (Heavenly Treasury); thus the government post and ward at the valley mouth are both named Tianzang. It is surmised that inside this mountain [the treasure] will only appear to the world when Maitreya descends to be born.
