The AA is divided into eight categories, which correspond to the eight chapters of the work, and (with one technical exception in chapter eight) to the eight "realizations" said to be necessary for full enlightenment. (Conze remarks that these eight are "not attested elsewhere.") This division into eight appears thus at the beginning of the AA itself: :[The Buddhas] proclaim the
Perfection of Wisdom [
Sūtra] by way of eight subjects. These eight are the knowledge of all aspects, knowledge of paths, and all knowledge. Then there is the awakening to all aspects, when culmination is attained, serial, awakening in an instant, and the Truth Body. [AA verses 1.4 and 1.5, Sparham translation] These eight categories naturally fall into three groups, as shown below. The seventy topics (here enumerated but not shown) are their subdivisions. Obermiller traces this list to a manual attributed to
'Jam dbyangs Bzhad pa, who also created the various definitions and category-boundaries familiar to Tibetan debaters. The text may be subdivided further still, into 1,200 items. Unless otherwise indicated, the English terms below follow Sparham's translation (which revises Conze's).
The Three Knowledges The first three categories represent the objects or goals of practice, whose attainment leads to peace for the four classes of Buddhist practitioner. Obermiller calls them "the 3 Kinds of Omniscience," while Toh prefers "the Three Exalted Knowers" and Berzin, "the Three Sets of Realized Awareness." :1. Knowledge of all aspects ::(

9 topics ::(Wisdom attained by
sravakas and
pratyekabuddhas, i.e.,
Hinayana practitioners) Berzin explains these categories as :"...groupings of realizations gained by the three sets of
aryas ('
phags-pa, highly realized beings), those who have gained nonconceptual cognition of the sixteen aspects of the
four noble truths. The three are organized into basis, pathway, and resultant stages and thus, in a complex manner, are cumulative. They are studied, however, in reverse order to their attainment, in order to inspire interest in developing them."
Sravakas and
Pratyekabuddhas, in order to discern the truths of
anitya (impermanence),
anatman (selflessness), and
dukha (suffering), must acquire knowledge of the fundamental constituents of reality (
vastu)--namely the
skandhas,
ayatanas, and
dhatus which are the subjects of
Abhidharma. This is the "all-knowledge" of chapter three. A bodhisattva, in order to benefit all sentient beings, must additionally cognize the various possible paths by which others may progress, so that he may, for example, teach in different ways in accordance with their various situations and capacities. This is the "knowledge of paths" of chapter two. According to the Mahayana understanding, only a fully enlightened Buddha has eliminated obstacles to omniscience (
jneyavaranaheya) as well as obstacles to liberation (
kleshavaranaheya). "Knowledge of all aspects" in the first chapter refers to this ultimate state. The AA begins with this as the most impressive of the three, and the ultimate goal of the Mahayana practitioner.
The Four Practices Categories four through seven (in this order) represent progressive stages of spiritual practice en route to enlightenment. Conze calls them four "understandings"; Obermiller, "practical methods"; Toh, "applications"; and Berzin (who notes the close connection to "yoga," ngal sbyor), "applied realizations." :4.

4 topics Referring to the above, Dreyfus explains that :"...the
Ornament presents the four practices or realizations [chapters 4-7], emphasizing particularly 'the practice of all the aspects' (), which is treated in the fourth chapter. In fact, that practice is the central topic of the text and may have been an actual practice in which all the aspects of the three wisdoms [chapters 1-3] are brought together... But--and this point is crucial--no teacher I have ever met seems to have practiced this meditation, or even to have been clear on how to do so... Clearly the work's central themes are not practiced in the Tibetan scholastic traditions." Tibetan tradition lays special emphasis on chapter four, perhaps because it is the longest and most complex, and therefore best suited to commentary and debate. This fourth chapter enumerates, and extensively describes, (in Obermiller's words) "173 forms of the Bodhisattva's
yoga as realizing respectively the 173 aspects (of the 3 forms of Omniscience)."
The Resultant Truth Body The last Category concerns the result of spiritual practice: :8. The Resultant Truth Body ::(
Dharmakāyābhisambodha, chos sku)........................................
4 topics :::::::::::::::: -------------- ::::::::::::::::
70 topics By this is meant the
Dharmakāya, one of several glorified spiritual bodies (Makransky prefers "embodiments") which a Buddha is said to possess. A commentarial tradition beginning with Arya Vimuktisena interprets the AA as teaching the existence of three such bodies (the
trikaya doctrine); a rival tradition follows Haribhadra in identifying four such bodies, with the fourth, disputed
kāya being the
Svabhāvikakāya (Tib. ngo bo nyid kyi sku) or "Nature / Essence Body". (Other writers interpret this last term as a synonym for Dharmakaya, or else as symbolizing the unity of the three.) Makransky, whose
Buddhism Embodied focuses on this eighth chapter of the AA, writes that :"Haribhadra had read
AA 8 as a systematic treatise whose purpose was to present a logically coherent model of Buddhahood. His perspective owed much to Buddhist logic and Abhidharma traditions that had sought such systematic coherence. Ratnākarāśānti, basing himself instead on the perspective on nondual yogic traditions, specifically understood the terms
svābhāvikakāya and
dharmakāya in
AA 8 (and throughout Mahāyana literature) to refer to a Buddha's
own perspective on the nature of his attainment,
not to a human perspective on it. [...] Tsong kha pa, influenced by the logico-epistemological approach expressed in Haribhadra's work, supported his interpretation of
AA 8.
Go ram pa, drawing from a perspective framed by nondual yogic praxis, supported Ratnākorāśānti's call to return to Arya Vimuktisena's previous interpretation. Tsong kha pa and Go ram pa's interpretations are closely related to their differing perspectives on a Buddha's awareness, which was an explicit topic of discussion in
Candrakirti's
Mādhyamikāvatāra, upon which they both commented." For Makransky, the controversy reflects a fundamental tension between immanent and transcendent aspects of Buddhism, which is also reflected in debate over the
Three Turnings of the Wheel of Dharma, or gradual vs.
sudden enlightenment (as at
Samye). In his view, all these controversies stem from a fundamental difficulty in reconciling the transcendent nature of Buddhahood with the immanent nature of
bodhicitta. ==Ancillary Topics==
