佛說盂蘭盆經疏 2.63

2.63

"On this day, all the holy assembly—whether practicing dhyāna in the mountains, having attained the four fruits of the path, pacing in walking meditation beneath trees, freely using the six supernormal powers to instruct and transform śrāvakas and pratyekabuddhas, or great bodhisattvas of the ten grounds provisionally appearing as monks amid the great assembly—all with one mind receive the rice in the pātra. The path of the holy assembly endowed with pure precepts has vast and boundless virtue."
