佛說觀佛三昧海經 9.20

9.20

財首菩薩所散諸華住阿難上者，化成華雲遍滿十方，一一雲間無數化佛，各申右手摩阿難頂告言：「法王子！諸佛如來所有化身，亦如我等，等無有異。汝今親見，當為未來一切眾生廣分別說，令諸眾生修行念佛。若念佛者，得見化佛與今無異，若有眾生聞汝所說，則為見佛除無量罪。」

The flowers scattered by Bodhisattva Dhanada that hovered above Ānanda transformed into clouds of flowers filling the ten directions. In each cloud were countless transformation Buddhas, each stretching out his right hand, stroking Ānanda's crown, and addressing him: "Prince of the Dharma! All the transformation bodies of the Buddha Tathāgatas are just like ours, equal and no different. Having seen them in person now, you should extensively and distinctly explain them for all sentient beings of the future, causing sentient beings to practice mindfulness of the Buddha. If they are mindful of the Buddha, they will see transformation Buddhas, equal and no different from today. If any sentient beings hear what you expound, that will constitute seeing the Buddha, and their immeasurable sins will be eradicated."
