Day 15 concludes Chapter 10, The Teacher of the Dharma, and opens Chapter 11, Beholding the Stūpa of Treasures.
Having last time witnessed the reaction of the four kinds of devotees to the arrival of the Stupa of Treasures, we consider Śākyamuni’s answer to why a voice was heard from within the stupa.
The Buddha said to him:
“The perfect body of a Tathāgata is in this stūpa of treasures. A long time ago there was a world called Treasure-Purity at the distance of many thousands of billions of asaṃkhyas of worlds to the east [of this world]. In that world lived a Buddha called Many-Treasures. When he was yet practicing the Way of Bodhisattvas, he made a great vow: ‘If anyone expounds a sūtra called the Lotus Flower of the Wonderful Dharma in any of the worlds of the ten quarters after I become a Buddha and pass away, I will cause my stūpa-mausoleum to spring up before him so that 1 may be able to prove the truthfulness of the sūtra and say ‘excellent’ in praise of him because I wish to hear that sūtra [directly from him].”
“He attained enlightenment[, and became a Buddha]. When he was about to pass away, he said to the bhikṣus in the presence of the great multitude of gods and men, ‘If you wish to make offerings to my perfect body after my extinction, erect a great stūpa!’
“If anyone expounds the Sūtra of the Lotus Flower of the Wonderful Dharma in any of the worlds of the ten quarters, that Buddha, by his supernatural powers and by the power of his vow, will cause the stūpa of treasures enshrining his perfect body to spring up before the expounder of the sūtra. Then he will praise [the expounder of the sūtra], saying, ‘Excellent, excellent!’
The Lecture on the Lotus Sūtra offers this note:
The speaker is a Buddha called Many-Treasures Tathagata (“Thus Come”), who resides within the stupa. Because he proves the authenticity of the Lotus Sutra, which is expounded by Sakyamuni, the World-Honored One, he is called the Validating Buddha. His Stupa is named the Stupa of Treasures.
