佛說觀佛三昧海經 4.52

4.52

When the Buddha entered this samādhi, the city of Kapilavastu, the Nyagrodhārāma, and Jambudvīpa appeared like a great jeweled flower. On the terrace of the flower was a crystal banner; at the tip of the crystal banner was a crystal mirror, in which the immeasurable pure lands of the Buddhas of the ten directions all manifested.
