Prabhūtaratna (Skt: प्रभूतरत्न; Traditional Chinese: 多寶; Simplified Chinese: 多宝; pinyin: duō bǎo; Japanese: 多宝如来 Ta takara nyorai or Tahō nyorai), also known as Abundant Treasures,
is the Buddha whom Shakyamuni is closely associated with in the Threefold Lotus Sutra, namely in the Lotus Sutra itself and the Samantabhadra Meditation Sutra.
In the Lotus Sutra
In the 11th chapter of the Lotus Sutra, Prabhūtaratna is depicted as seated next to Shakyamuni Buddha within the stupa of Abundant Treasures Buddha, to whom all the buddhas from the "ten directions," and those in the great assembly, come to hear the Dharma,
and is said to reside in a land "tens of millions of billions of countless worlds to the east" called "Treasure Purity".
Within a stupa called "Precious Stupa," or the "Stupa of the Precious Seven Materials",
is where Prabhūtaratna resides and in which he appears to manifest himself when bearing witness to the Lotus Sutra of the Wonderful Dharma.
This stupa is believed to symbolize buddha-nature which all people possess, while the springing-up of the stupa from the earth is said to imply the discovery of one's own buddha-nature.
