佛說觀佛三昧海經 1.59

1.59

"At that time Chandaka saw the ground in the palace appear like the color of crystal, solid inside and out like vajra. Treading on it without making a sound, he swiftly went to the rear stables, harnessed the horse with a golden saddle, and led him before the hall. Chandaka addressed the Prince, saying: 'The devas, gazing reverently with palms joined and hands clasped, abide in empty space, praising with one voice the merit of going forth. It is time for the Prince to mount the horse swiftly.'"
