大方便佛報恩經 3.12

3.12

At that time, the Tathāgata immediately entered the samādhi of forms. By the power of the samādhi, he caused the sound of the lute to be heard far across the trichiliocosm—its sound fully expounded suffering, emptiness, impermanence, impurity, and non-self. When heedless sentient beings heard this wondrous sound fully expound how the Tathāgata knows kindness and repays kindness, having filial devotion toward his parents for immeasurable asaṃkhyeya kalpas, all sentient beings followed the sound to Jambudvīpa, went to the Buddha's place, bowed their heads to his feet, and withdrew to sit to one side.
