Position summary
Thuken is the third Thuken hutuqtu, a Mongolian-heritage incarnate lama from Amdo (born Phüntsok Lungpa valley, now Gansu), educated at Gönlung Monastery and Drepung Gomang, and active across Amdo, central Tibet, Mongolia, and the Qing court at Beijing. His root teacher was Changkya Rölpai Dorjé (1717–86); other principal teachers include the Second Jamyang Shepa, the Third Panchen Lama, and Sumpa Khenpo. He served as abbot of Shalu, Gönlung, Jakhyung, and Kumbum at various points, and died at Gönlung in 1802 having completed the Crystal Mirror in early January of that year.
His one philosophically significant work for this wiki is the Grub mtha’ shel gyi me long — Crystal Mirror of Philosophical Systems — completed 1802 and added as thuken-crystal-mirror-1802. The work is a hybrid grub mtha’ / chos ‘byung / lo rgyus covering Indian Buddhist and non-Buddhist schools, all major Tibetan traditions including Bön, Chinese Confucian/Daoist/Buddhist, Mongolian, Khotanese, and Shambhalan. His other 250-odd texts are largely tantric ritual works (Hayagrīva, Vajrayoginī, etc.), monastic chronicles, biographies, and panegyric verse — not philosophically primary.
His doxographical position is canonically Geluk: Tsongkhapa as definitive commentator on Nāgārjuna; Prāsaṅgika as the highest tenet system; the framework of Two Truths, three turnings, and provisional/definitive as the structural basis for Mahāyāna interpretation. What is distinctive is the form of the inclusivism: as Roger Jackson reconstructs in his Editor’s Introduction (in thuken-crystal-mirror-1802), Thuken takes the Geluk to be supreme but explicitly rejects the harder claim that other Tibetan traditions cannot lead to liberation. Apart from a hard exclusion list (Jonang, Taktsang Lotsāwa, Shakya Chokden), every other Tibetan system is “pervaded by pure appearance” and capable of bringing about the soteriological aim.
Hermeneutical approach
Fully within the Mahāyāna hermeneutical framework. The framework is unmarked-default for Thuken — he does not argue for it, he operates from it. The interesting hermeneutical move is the form of his refutations: he refutes the Jonang at length on doxographical grounds (chapter 9), but refutes the misreadings of Madhyamaka view, meditation, and tantra in the Geluk chapter (chapter 12) without naming individual opponents — they are simply “some” or “others.” This is the late-Geluk synoptic style: doxographical positions are catalogued and refuted; specific opponents are named only when their positions are taken as the founding exemplar of an excluded view (Dölpopa for gzhan stong; Heshang for “thinking nothing”).
The most striking hermeneutical fact about the Crystal Mirror is the silence on Gorampa. Gorampa is named only as a monastery founder; his polemical Lta ba’i shan ‘byed — completed in 1469, banned by the Ganden Potrang post-1659, and the most sophisticated Sakya-side attack on the Geluk Madhyamaka — is not engaged. The asymmetry between Thuken’s exhaustive Jonang refutation and his complete silence on Gorampa is paper-relevant data: by 1800 in Geluk Amdo, Gorampa is excluded from the discourse rather than refuted in it.
Key claims
On the Indian Madhyamaka schools (chapter 2):
- Standard Geluk-doxographical four-school hierarchy with the Prāsaṅgika at the apex; Āryadeva and Nāgārjuna as “general Madhyamaka” whose ultimate meaning is Prāsaṅgika.
- Buddhapālita–Bhāviveka–Candrakīrti narrative for the founding of the Prāsaṅgika–Svātantrika distinction.
- Six terms for what the Prāsaṅgika negates that the Svātantrika accepts conventionally: “established by their own characteristics,” “inherently established,” “essentially established,” + the three the Svātantrika also negates (“truly established,” “perfectly established,” “ultimately established,” “established in reality,” “established by their own entity”) — almost identical to Tsongkhapa’s six-fold list in Illuminating the Intent Ch 9.
On the Jonang (chapter 9):
- Gzhan stong is structurally Hindu, paralleled in three load-bearing respects with Brahman-as-sound (Śabda-Brahman), Sāṃkhya, and Vedānta+Mīmāṃsaka. This is Thuken’s distinctive contribution to the anti-zhentong literature; an external structural reduction that complements Red mda’ ba’s internal one (transmitted via Gorampa ).
- The Laṅkāvatāra passage on tathāgatagarbha is read as the Buddha’s own explicit neyārtha statement: tathāgatagarbha is taught for the meaning of “emptiness; the absolute limit; nirvana; the unarisen; the signless; the wishless; and the empty,” to attract those who fear selflessness.
- Catalogue of pre-Tsongkhapa Tibetan critics of the Jonang: Butön, his disciple Lotsāwa Rinchen Namgyal, Tsöndrü Pal, Yardrokpa Rinchen Tok, Nedrukpa Gendün Pal, Rinchen Shönu, Kashipa Rinchen Dorjé. Confirms the chronology already established at gorampa-distinguishing-views-1469 via Drakpa Gyaltsen.
On the Geluk’s distinctiveness in view (chapter 12):
- Catalogues three excluded positions: (i) deflationism (emptiness = nothingness, Lokāyata); (ii) eternalism (zhentong, “extrinsic emptiness as the final ultimate nature”); (iii) Heshang-quietism (“thinking nothing”). All three are refuted on the same ground: Madhyamaka requires both thoroughly refuting the object of refutation (inherent existence) and knowing how to determine, non-nihilistically, the residue of dependent-origination conventional truth. Direct restatement of framework-absence-yields-nihilism in late-Geluk doxographical form.
On Atiśa (chapter 5):
- Reads Atiśa as straightforwardly Prāsaṅgika-via-Candrakīrti — a reading that conflicts with apple-jewels-middle-way-2018’s manuscript-based reconstruction of Atiśa’s pre-distinction “Great Madhyamaka.”
On Shakya Chokden:
- Hostile deathbed-recantation hagiography, sharply contradicted by komarovski-visions-unity-2011’s reconstruction of Shakya Chokden’s mature corpus.
