On Yuan Chwang's Travels in India, 629–645 A.D. v1.c13.s2.6

v1.c13.s2.6

The Tushita Paradise, as is well known, is the Heaven in which the Bodhisattva Maitreya sojourns between his last incarnation on earth and his future advent as Buddha. The Śāstra-master Guṇaprabha in this passage considers himself, as a fully ordained Buddhist bhikshu, to be superior to the Bodhisattva who was enjoying the pleasures of a prolonged residence in Paradise; and accordingly Guṇaprabha persists in his refusal to show to Maitreya the reverence due to a great Bodhisattva, and consequently fails in his career.
