Chapters 17-24 contain some of the Diamond Sutra's most challenging and most quoted teachings. Here the Buddha says that supreme enlightenment is not something one can attain as a possession, that past mind, present mind, and future mind cannot be grasped, and that even the Dharma must not become another object of attachment.
Read together, these chapters strip away spiritual ambition at its root. They show why a bodhisattva can vow to liberate all beings without clinging to the idea of a self who saves, a being who is saved, or a teaching that can be owned. What remains is a path of wisdom, practice, and compassion without grasping.
第十七品 究竟無我分
爾時，須菩提白佛言：「世尊！善男子、善女人，發阿耨多羅三藐三菩提心，云何應住？云何降伏其心？」佛告須菩提：「善男子、善女人，發阿耨多羅三藐三菩提心者，當生如是心，我應滅度一切眾生。滅度一切眾生已，而無有一眾生實滅度者。何以故？須菩提！若菩薩有我相、人相、眾生相、壽者相，則非菩薩。所以者何？須菩提！實無有法發阿耨多羅三藐三菩提心者。」「須菩提！於意云何？如來於燃燈佛所，有法得阿耨多羅三藐三菩提不？」「不也，世尊！如我解佛所說義，佛於燃燈佛所，無有法得阿耨多羅三藐三菩提。」佛言：「如是！如是！須菩提！實無有法如來得阿耨多羅三藐三菩提。須菩提！若有法如來得阿耨多羅三藐三菩提者，燃燈佛則不與我授記：汝於來世，當得作佛，號釋迦牟尼。以實無有法得阿耨多羅三藐三菩提，是故燃燈佛與我授記，作是言：『汝於來世，當得作佛，號釋迦牟尼。』何以故？如來者，即諸法如義。若有人言：『如來得阿耨多羅三藐三菩提』。須菩提！實無有法，佛得阿耨多羅三藐三菩提。須菩提！如來所得阿耨多羅三藐三菩提，於是中無實無虛。是故如來說：一切法皆是佛法。須菩提！所言一切法者，即非一切法，是故名一切法。須菩提！譬如人身長大。」須菩提言：「世尊！如來說：人身長大，則為非大身，是名大身。」「須菩提！菩薩亦如是。若作是言：『我當滅度無量眾生』，則不名菩薩。何以故？須菩提！實無有法名為菩薩。是故佛說：一切法無我、無人、無眾生、無壽者。須菩提！若菩薩作是言，『我當莊嚴佛土』，是不名菩薩。何以故？如來說：莊嚴佛土者，即非莊嚴，是名莊嚴。須菩提！若菩薩通達無我法者，如來說名真是菩薩。」
Interpretation: This chapter returns to the sutra's central question: how should someone who has raised the mind of awakening live and train? The Buddha answers by holding together two truths at once. A bodhisattva vows to liberate all beings, yet in ultimate truth no being can be grasped as something fixed that is "saved." If one still clings to the four marks of self, person, being, and life span, one has not yet entered the bodhisattva path in its full sense.
The chapter then goes further. The Buddha says there is in fact no dharma that can be attained as supreme enlightenment. He even uses his own meeting with Dīpaṃkara Buddha to make the point: if awakening were something that could be acquired like an object, there would have been something concrete to receive. Instead, Buddhahood is confirmed precisely because there is nothing to grasp. This is why the sutra can say that all dharmas are Buddha Dharma and immediately add that they are "not" all dharmas. The point is not denial for its own sake. It is to free the mind from turning even the path into another possession. A true bodhisattva works for beings without building an ego around doing so.
第十八品 一體同觀分
「須菩提！於意云何？如來有肉眼不？」「如是，世尊！如來有肉眼。」「須菩提！於意云何？如來有天眼不？」「如是，世尊！如來有天眼。」「須菩提！於意云何？如來有慧眼不？」「如是，世尊！如來有慧眼。」「須菩提！於意云何？如來有法眼不？」「如是，世尊！如來有法眼。」「須菩提！於意云何？如來有佛眼不？」「如是，世尊！如來有佛眼。」「須菩提！於意云何？如恆河中所有沙，佛說是沙不？」「如是，世尊！如來說是沙。」「須菩提！於意云何？如一恆河中所有沙，有如是等恆河，是諸恆河所有沙數，佛世界如是，寧為多不？」「甚多，世尊！」佛告須菩提：「爾所國土中，所有眾生，若干種心，如來悉知。何以故？如來說：諸心皆為非心，是名為心。所以者何？須菩提！過去心不可得，現在心不可得，未來心不可得。」
Interpretation: This chapter turns to the Buddha's "five eyes" and to one of the sutra's most famous lines: past mind cannot be grasped, present mind cannot be grasped, future mind cannot be grasped. The discussion of the five eyes shows that the Buddha sees at every level, from ordinary appearances to the ultimate nature of things. He knows the countless minds of beings across immeasurable worlds, yet he immediately undercuts any attempt to treat those minds as fixed entities.
That is the force of saying that "all minds are not mind; they are merely called mind." Thoughts arise, shift, and vanish. The past is gone, the future has not arrived, and even the present does not remain long enough to be possessed. The sutra is not denying that mind functions. It is warning against grasping at mental states as though they had lasting substance. This chapter invites the reader to see awareness as conditioned, fluid, and empty of fixed essence.
第十九品 法界通化分
「須菩提！於意云何？若有人滿三千大千世界七寶以用布施，是人以是因緣，得福多不？」「如是，世尊！此人以是因緣，得福甚多。」「須菩提！若福德有實，如來不說得福德多；以福德無故，如來說得福德多。」
Interpretation: This short chapter contrasts material giving with the wisdom of Prajñā. Offering treasures that fill entire world systems produces immense merit at the conventional level. But the Buddha immediately qualifies that merit: if it were something solid and ownable, it would not be called truly great. Merit becomes vast precisely when one does not cling to it.
The point is not to dismiss generosity. The sutra is correcting the mind that secretly turns good deeds into spiritual property. When giving is practiced without attachment to giver, gift, or receiver, its value is no longer trapped inside ego and calculation. That is why merit grounded in wisdom and non-grasping is called greater.
第二十品 離色離相分
「須菩提！於意云何？佛可以具足色身見不？」「不也，世尊！如來不應以具足色身見。何以故？如來說：具足色身，即非具足色身，是名具足色身。」「須菩提！於意云何？如來可以具足諸相見不？」「不也，世尊！如來不應以具足諸相見。何以故？如來說：諸相具足，即非具足，是名諸相具足。」
Interpretation: This chapter returns to a central Diamond Sutra theme: the Tathāgata cannot be known through appearances alone. Even the Buddha's perfected body and auspicious marks are not the final truth of Buddhahood. They are skillful forms that appear within conditions, not the Dharma-body itself.
For that reason, the sutra repeats its familiar pattern: what is called the "complete body" is not a complete body in any ultimate sense; it is only provisionally named. The warning is clear. If we seek the Buddha only in visible form, we confuse symbol with reality. True seeing moves beyond form and mark.
第二十一品 非說所說分
「須菩提！汝勿謂如來作是念：『我當有所說法。』莫作是念，何以故？若人言：如來有所說法，即為謗佛，不能解我所說故。須菩提！說法者，無法可說，是名說法。」爾時，慧命須菩提白佛言：「世尊！頗有眾生，於未來世，聞說是法，生信心不？」佛言：「須菩提！彼非眾生，非不眾生。何以故？須菩提！眾生眾生者，如來說非眾生，是名眾生。」
Interpretation: This chapter dismantles attachment to the teaching act itself. The Buddha warns Subhuti not to imagine that the Tathāgata possesses some fixed doctrine that can be handed over like an object. If someone insists that "the Buddha preached a Dharma" in that concrete sense, they have already missed the point of the sutra.
When the text says "there is no dharma that can be spoken; this is called speaking the Dharma," it is not rejecting language altogether. It is pointing out that words are provisional tools, not the truth they indicate. The same logic applies to sentient beings. They are conventionally called beings, yet no fixed essence can be found behind the name. This chapter pushes the reader away from verbal reification and back toward direct insight.
第二十二品 無法可得分
須菩提白佛言：「世尊！佛得阿耨多羅三藐三菩提，為無所得耶？」佛言：「如是，如是。須菩提！我於阿耨多羅三藐三菩提乃至無有少法可得，是名阿耨多羅三藐三菩提。」
Interpretation: This chapter condenses the whole force of the sutra into one direct exchange. Subhuti asks whether the Buddha, in attaining unsurpassed awakening, actually obtained nothing. The Buddha answers yes. Not even the slightest dharma was gained, and precisely for that reason it is called supreme awakening.
This is the Diamond Sutra's teaching on no attainment in its most concentrated form. Enlightenment is not the acquisition of a spiritual object, a permanent state, or a special possession. It is freedom from grasping. Because there is nothing fixed to own, there is nothing fixed to attain. The name "awakening" remains useful, but the mind must not turn it into another thing to seize.
第二十三品 淨心行善分
復次，須菩提！是法平等，無有高下，是名阿耨多羅三藐三菩提；以無我、無人、無眾生、無壽者，修一切善法，即得阿耨多羅三藐三菩提。須菩提！所言善法者，如來說即非善法，是名善法。
Interpretation: This chapter shows how wisdom and ethical action belong together. Supreme awakening is described as equal and without hierarchy. It is realized by practicing all wholesome dharmas without clinging to self, person, being, or life span. In other words, emptiness does not cancel moral action. It purifies the mind within action.
That is why the Buddha can say that wholesome dharmas are "not" wholesome dharmas and are therefore called wholesome dharmas. Goodness is not denied. Rather, the chapter protects it from pride and attachment. A bodhisattva still acts for the welfare of beings, but does not build an identity out of doing good.
第二十四品 福智無比分
「須菩提！若三千大千世界中所有諸須彌山王，如是等七寶聚，有人持用布施；若人以此《般若波羅蜜經》，乃至四句偈等，受持讀誦、為他人說，於前福德百分不及一，百千萬億分，乃至算數譬喻所不能及。」
Interpretation: This chapter again contrasts material generosity with preserving, reciting, and explaining even a short portion of the Prajñāpāramitā teaching. The scale of the comparison is deliberately overwhelming: treasures as vast as countless Mount Sumerus are still inferior to the merit of transmitting wisdom.
Why? Because material giving benefits conditioned life within saṃsāra, while Prajñā addresses the root of liberation itself. The chapter is not scorning generosity. It is placing wisdom at the center. Without wisdom, merit remains limited. With wisdom, even a brief verse can open the way beyond attachment and toward awakening.
