Vagrakkhedikâ (Diamond-cutter), section 24

And if, O Subhuti, a woman or man, putting together as many heaps of the seven treasures as there are Sumerus, kings of mountains, in the sphere of a million millions of worlds, should give them as a gift to holy and fully enlightened Tathagatas; and if a son or a daughter of a good family, after taking from this treatise of the Law, this Prajñāpāramitā, one Gāthā of four lines only, should teach it to others, then, O Subhuti, compared with his stock of merit, the former stock of merit would not come to the one hundredth part, &c., till ‘it will not bear an approach.’ (24)
