坐禪三昧經 1.88

1.88

爾時，復念二佛神德，三四五佛乃至無量盡虛空界，皆悉如是。復還見一佛，能見一佛作十方佛，能見十方佛作一佛。能令一色作金、銀、水精、毘琉璃色，隨人意樂悉令見之。

At that time, one further recollects the divine virtues of two Buddhas, three, four, five Buddhas, up to an immeasurable number filling the entire realm of empty space, all in the same manner. Then one returns to seeing one Buddha; one can see one Buddha become the Buddhas of the ten directions, and one can see the Buddhas of the ten directions become one Buddha. One can make a single color become the colors of gold, silver, crystal, and lapis lazuli, making them all visible according to what people wish to see.
