佛說觀佛三昧海經 2.30

2.30

「此相現時，佛菩提樹，白毛力故根下自然化生寶華，縱廣正等四十由旬，其華金色金剛為臺。佛眉間光照此華臺，其光直下至金剛際，於金剛際自然化生二金剛座，互相掁觸，聲振三千大千世界，令此大地六種振動。其金剛座上衝蓮華，至蓮華根，其蓮華根亦是金剛，三種金剛共相掁觸，直還下過至金剛際往旋十返，白毫光明圍遶十匝，令金剛座鏗然不動。

“When this mark appeared, beneath the roots of the Buddha’s Bodhi tree, by the power of the white ūrṇā-hair, a jewelled lotus spontaneously manifested, forty yojanas in length and breadth evenly, with golden petals and an adamantine dais. The light from between the Buddha’s brows shone upon this flower dais, and its radiance went straight downward to the adamantine limit, where two adamantine seats were spontaneously manifested at the adamantine limit. Striking against each other, their sound shook the trichiliocosm, causing this great earth to shake in six ways. Those adamantine seats surged upward toward the lotus flower, reaching its root. The root of that lotus was also adamantine; the three adamantine elements struck one another, turned straight back down, passed through to the adamantine limit, revolving back and forth ten times. The radiance of the white ūrṇā encircled them in ten circuits, rendering the adamantine seats resolutely unshakeable.
