佛說觀佛三昧海經 9.42

9.42

At that time, the Bhagavat, again for the sake of all sentient beings of future ages, further spoke on the method of contemplating the seated image: "Regarding contemplating the seated image: With utmost sincerity, one fixes mindfulness and causes flowers to emerge beneath the feet of the standing image in front. When these flowers emerge, one should give rise to the visualization: 'Let this great earth become golden in color, become the color of the seven treasures.' Manifesting in accordance with the visualization, each treasure color has gold as its boundary, and between each boundary, treasure lotuses are born. When forming this visualization, there are treasure lotuses fully endowed with a thousand petals, appearing according to the visualization. Having seen the flowers, one invites the visualized images to sit upon the treasure lotuses. When the images sit, the great earth spontaneously emits a great white light, like the color of vaiḍūrya, purely white and lovely. Amidst the white lights, a hundred koṭis of bodhisattvas, white as snowy mountains, emerge from the pores of the visualized images' bodies. From the pores of each bodhisattva's body, golden light comes forth; the light is like mountains, hundreds of thousands of golden hues like Jāmbūnada gold, its brilliance dazzling and its measure uncountable, appearing according to the visualization. Atop each mountain peak, there is a visualized image, lofty, prominent, and sightly, the color of Jāmbūnada gold, its light exceedingly magnificent, illuminating the realms of the ten directions so that all become golden; one sees the earth and the sky also turn golden, completely filled with golden images, golden light, golden canopies, golden terraces, golden flowers, and golden pennants. One sees the visualized bodhisattvas of pure white jade color, holding white whisks in their hands or holding white flowers; one should give rise to the visualization, making them intensely pure white. If other mixed thoughts and different realms appear, one should quickly eradicate them; if one does not eradicate them and instead follows other thoughts, following other realms, it will easily induce wind disorders. This mindfulness of the Buddha is the great amṛta that benefits sentient beings. The buddhānusmṛti-samādhi is like taking good medicine that benefits the four elements; those who take this medicine will not age and will not die."
