The Long Āgama Sūtra 4.22

4.22

「時，毗沙門王聞此偈已，歡喜而言：『世尊出世說真實法，甚奇！甚特！未曾有也。我本不知如來出世，說如是法。於未來世，當復有佛說如是法，能使忉利諸天發歡喜心。』

“‘Upon hearing these verses, King Vaiśravaṇa rejoiced and said, “The Bhagavān has appeared in the world and teaches the true Dharma. It’s amazing, extraordinary, and unprecedented! I didn’t know a Tathāgata arose in the world and taught such a Dharma in the past, and there will again be a Buddha in the future who teaches such a Dharma that will cause the Trāyastriṃśa gods to rejoice at heart.”
