佛說觀佛三昧海經 4.34

4.34

“Hundreds of millions of rays of light illuminate the southern direction, causing the earth of the southern direction to become entirely red in color. This red light extends to the immeasurable worlds of the southern direction and transforms into white clouds, red and white clearly distinct. Amidst the clouds are transformation Buddhas of the color of white pearls and the radiance of vaiḍūrya, with superior and wondrous golden flowers serving as the Buddha seats. Atop the golden flowers are ten billion bodhisattvas, all of golden-yellow color, with ten billion jeweled rays of light outshining the white clouds. In each ray of light are five hundred transformation Buddhas; these transformation Buddhas, with different mouths but a single voice, also praise non-killing and great loving-kindness and compassion. One who contemplates in this way is termed one who practices right contemplation; if one contemplates otherwise, it is termed wrong contemplation.”
