Subhúti, be mindful not to speak after this manner, “Tathágata has this intention in his heart, viz., ‘I ought to have a definitely declared system of doctrine,’” never think thus. For why, if a man say that Tathágata has a definitely spoken system of doctrine, that man does but malign Buddha, for the law which I give cannot be explained in words. Subhúti, as to a definitely declared system of law, that which can be thus declared is no law, it is but an empty name. At this time the aged sage Subhúti addressed Buddha thus: World-honoured one! will the mass of sentient beings who in future years may listen to this law, will they hereby have begotten in them a believing heart? Buddha said: Subhúti, that mass of sentient beings, of which you speak, in one sense is real, and in another is unreal. But what then, Subhúti? the mass of sentient beings, born of sentient beings, Tathágata declares are no such beings at all; the term “sentient beings” is but a name. _Cap. XXII.—It is wrong also to say that this system or condition of being can be attained to._ Subhúti addressed Buddha thus: World-honoured one! Buddha having arrived at the condition of the unsurpassed and perfect heart, is he in the condition which has previously been described as “not to be attained?” Buddha said: True, True, Subhúti! I, as possessed of this heart, have come into the condition above described. This term the unsurpassed, just, and enlightened heart, is but a mere name. _Cap. XXIII.—The heart purified leads to virtuous practice._ Moreover, Subhúti, this condition of being of which I speak is one and uniform. There is no such thing as high or low in it. This condition which is named the unsurpassed, just, and enlightened (heart), consists in nothing more than the exclusion of all individual distinctions. A man who practises all the rules of virtuous conduct will forthwith attain this condition. But, Subhúti, when we speak of rules of virtuous conduct, Tathágata declares that these rules are after all no real and lasting rules; the term is but a mere name. _Cap. XXIV.—On the incomparable character of the happiness consequent on this wisdom._ Subhúti, if all the royal Sumerus in the great chiliocosm were gathered together, and a man were to distribute in charity an amount of the seven precious substances equal to this accumulated mass, and if another man were to accept and adopt this Prajná-páramitá Sútra, up to the point of the four canons, and read and recite it, on account of that man, I declare that his happiness and consequent merit would be incomparably greater than that of the other, so much so, that no number could express the excess of one over the other. _Cap. XXV.—The non-reality of transformational differences._
