佛說觀佛三昧海經 9.42

9.42

爾時世尊復為來世諸眾生故，更說觀像坐法：「觀像坐者：至心繫念令前立像足下生華，此華生時當起想念：『令此大地作黃金色、作七寶色。』隨想而現，一一寶色黃金為界；一一界間生寶蓮華。作此想時有寶蓮華千葉具足，應想而現。既見花已，請諸想像令坐寶華。眾像坐時大地自然出大白光，如琉璃色白淨可愛，眾白光間百億菩薩白如雪山，從想像身毛孔中出，一一菩薩身毛孔中，出金色光其光如山，百千金色閻浮檀金，光明赫奕數不可知，應想而現；一一山頂有一想像高顯可觀，閻浮檀金色其光大盛，照十方界皆作金色，見地及空亦作金色，滿中金像、金光、金蓋、金臺、金華、金幡。見想菩薩純白玉色，手執白拂有執白華，當起想念極令鮮白。若餘雜想異境界現當疾除滅，若不除滅隨逐餘想，隨他境界喜發風病。此念佛想，是大甘露利益眾生，觀佛三昧，如服良藥利益四大，服此藥者不老不死。」

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."
