(Volume 2 of Records of high Priests in the Song Dynasty)
In midyear Da Li (770 AD) during the Tang dynasty, Dharma Master Fa Zhao, a bhiksu from the Yun Feng Monastery in Nanfei, went to Wu Tai Mountain to pay respects to the Vajra Cave with the hope of meeting Manjushri Bodhisattva. He bowed continuously until late at night and still failed to see the sagely countenance of Manjushri Bodhisattva. Blaming his own deep karmic obstructions, he prostrated himself on the ground and sincerely repented.
Suddenly, he saw a monk, who was about seven feet tall and spoke fluent Sanskrit in a sonorous tone. The monk introduced himself as Buddhapala and asked Fa Zhao, "Dharma Master, you have blamed yourself with such grief and persistence. May I know what is it that you wish to seek?"
Fa Zhao answered, "1 wish to meet Manjushri Bodhisattva !"
Buddhapala replied, "If your intention and determination are strong enough, and can bring forth a truly sincere mind, please take off your shoes and leave them on the board. The sagely countenance of Manjushri Bodhisattva will appear in front of you."
Fa Zhao placed his shoes as instructed. Not long after closing his eyes, he found himself in the Vajra Cave and saw a monastery with an entrance labelled 'Vajra Prajna Monastery'. The words written on the label were straight, bold and they glittered brightly. The monastery was
adorned with various precious jewels, their names and types were too many to mention. There were numerous raised pavilions and palaces everywhere, within which were screens arranged closely. Sounds of tinkling bells could also be heard.
There were collections of secret Tripitakas at about two hundred locations, which comprised "Vajra Prajna" and all other Sutras and Dharma. The people there had huge physique, unlike the body size that was normally seen.
The countenance of Manjushri Bodhisattva was very dignified and solemn.Manjushri Bodhisattva had many foilowers, and he also expressed his regards and concerns for Fa Zhao. After Fa Zhao had his tea, Buddhapala guided him out of Vajra Cave. Fa Zhao begged to remain in the monastery, but Buddhapala refused him. Before his departure, Fa Zhao was advised and encouraged to cultivate diligently by Buddhapala. If Fa Zhao could return, he would be allowed to stay in the monastery. When Fa Zhao was back on the board to put on his shoes, he turned around but Buddhapala was already nowhere to be seen.
