佛說觀佛三昧海經 3.26

3.26

“One ray shines upward from Jambudvīpa to the palaces of the Four Heavenly Kings, causing the Four Heavenly Kings to all see the Bhagavat Śākyamuni, the Sun among Men, riding upon a seven-jeweled terrace and proceeding with the great assembly to that heaven. Having seen him, the devas arouse the bodhicitta. This extends to all the devas of the formless realm, who all see this mark clearly and distinctly without confusion in their minds, causing the formless realm devas not to slander nirvāṇa and to give rise to the aspiration for bodhi.
