The Vajra Prajna Paramita Sutra
8. Emerging from the Dharma
“Subhuti, what do you think, if someone filled three thousand great thousand world systems with the seven precious gems and gave them as a gift, would he obtain many blessings and virtue?”
Subhuti said, “Very many, World Honored One. And why? Such blessings and virtue are not of the nature of blessings and virtue. Therefore the Tathagata speaks of many blessings and virtue.”
“If, on the other hand, a person were to receive and hold from this sutra even so few as four lines of verse and speak them for others, his blessings would surpass the previous ones. And why? Subhuti, all Buddhas and all Buddhas’ dharma of anuttarasamyaksambodhi come forth from this sutra. Subhuti, the Buddhadharmas spoken are no Buddhadharmas.
