Tibetan Buddhism is conventionally divided into four schools. They share a canon, a Vinaya lineage, the Madhyamaka philosophical framework, and the full tantric apparatus. Their differences are of lineage, emphasis, and — in a few genuinely substantive cases — doctrine.

The primary organising distinction is chronological. Nyingma means “ancient”: it descends from the earlier diffusion of the eighth and ninth centuries and works from the old translations. The other three are sarma, “new”: they descend from the later diffusion beginning in the eleventh century, with translations made under the standardised vocabulary established in the ninth.

Nyingma #

Founded: the earlier diffusion, 8th–9th c. Founding figure: Padmasambhava, together with Shantarakshita and King Trisong Detsen. Principal practice: Dzogchen, the Great Perfection.

Nyingma is the least centralised of the four. It has no single head — the position of Nyingma head has rotated among senior lamas by agreement since the 1960s — and it has historically had the strongest non-monastic component: ngakpa, married yogic practitioners with long hair and white robes, who hold lineages and transmit them within families.

Its distinctive textual mechanism is the terma tradition: treasures concealed by Padmasambhava and Yeshe Tsogyal and discovered centuries later by tertöns, treasure revealers. This provides a channel for ongoing revelation that the other schools do not have, and it has produced an enormous literature — including the Bardo Thodol, the Tibetan Book of the Dead. See The Terma Tradition.

Nyingma organises the whole of Buddhism into nine vehicles, culminating in atiyoga — Dzogchen — as the highest.

Major monasteries: Mindrolling, Dzogchen, Shechen, Palyul, Kathok, Dorje Drak.

Kagyu #

Founded: 11th c. Lineage: Tilopa → Naropa (India) → Marpa the Translator → Milarepa → Gampopa. Principal practice: Mahamudra, and the Six Yogas of Naropa.

Kagyu means “oral lineage,” and the school’s identity is transmission from teacher to student rather than textual scholarship — though Kagyu produced plenty of the latter too.

Milarepa (1052–1135) is Tibet’s most beloved religious figure and one of the great characters in religious biography: a young man who used black magic to kill his relatives in a family property dispute, sought out Marpa in remorse, was subjected to years of brutal trials — building and demolishing towers by hand, repeatedly — and finally received the teachings, retreated to caves, lived on nettles until he turned green, and taught in songs. The Hundred Thousand Songs of Milarepa is a genuine work of literature.

Gampopa (1079–1153) brought the Kadam monastic and lamrim tradition together with Milarepa’s yogic transmission, giving Kagyu its dual character: rigorous monastic institutions alongside a strong retreat and yogic tradition, including the classic three-year retreat.

Kagyu divided into several sub-schools. The Karma Kagyu, headed by the Karmapa, is the largest; the Karmapa line, beginning in the twelfth century, is the oldest formally recognised tulku lineage in Tibet, predating the Dalai Lamas by centuries. Drikung, Drukpa (the state religion of Bhutan), and Taklung are other major branches.

The Karmapa succession has been disputed since 1992, with two candidates recognised by different factions — a dispute entangled with Chinese and Indian politics and not resolved.

Sakya #

Founded: 1073, with the establishment of Sakya monastery by Khon Konchok Gyalpo. Principal practice: Lamdre, “the path and its fruit,” based on the Hevajra Tantra.

Sakya is the school of scholarship and of hereditary transmission. Leadership passes within the Khon family, which traces itself to the imperial period, and the current Sakya Trizin heads a lineage that has been continuous for nearly a thousand years.

Its great figure is Sakya Pandita (1182–1251), one of Tibet’s finest scholars, author of works on logic, poetics, and doctrine, and a sharp critic of what he regarded as sloppy Mahamudra teaching — his polemic against “Chinese Dzogchen” is discussed in Dzogchen and Mahamudra.

His nephew Chögyal Phagpa became imperial preceptor to Kublai Khan, and under Mongol patronage the Sakya school governed Tibet from roughly 1264 to 1354 — the first time a Buddhist school held temporal power there, and the origin of the “priest–patron” (chöyön) relationship that structured Tibetan-Mongol and later Tibetan-Chinese political theory.

Sakya also holds the shentong-adjacent debates at arm’s length and has its own distinctive position on the relationship between emptiness and appearance.

Geluk #

Founded: early 15th c. Founder: Tsongkhapa (1357–1419). Principal emphasis: monastic discipline, systematic study, formal debate, and Prasangika Madhyamaka.

Geluk means “virtuous way,” and the school began as a reform. Tsongkhapa’s programme insisted on strict Vinaya observance including celibacy, on extensive study before tantric practice, and on a specific and demanding interpretation of Madhyamaka — that emptiness is the absence of intrinsic existence and that conventional reality is fully preserved rather than undermined by it.

His Lamrim Chenmo, the Great Treatise on the Stages of the Path, is the school’s foundational work and one of the most comprehensive presentations of the whole path in any Buddhist tradition.

Geluk built the great monastic universities — Ganden, Drepung, Sera, and later Tashilhunpo — which before 1959 housed many thousands of monks each and ran a curriculum taking decades, culminating in the geshe degree. Formal debate, conducted with a distinctive clapping gesture, is the central pedagogical method and is still practised daily in the re-established monasteries in south India.

From the seventeenth century, with Mongol military backing, the Geluk school and the Dalai Lama institution governed Tibet. That political dominance is a significant part of why the school is the largest, and it produced episodes the tradition does not dwell on — including the suppression of the Jonang school over the shentong question.

Bon #

Often described as a fifth tradition, and formally recognised as such by the Tibetan administration in exile since 1977.

Bon presents itself as pre-Buddhist, founded by Tonpa Shenrab in the land of Olmo Lungring, and preserving teachings older than Shakyamuni’s. Scholarship generally regards organised Bon as having taken its present shape in the tenth and eleventh centuries, in close interaction with Buddhism, drawing on genuinely pre-Buddhist material but not straightforwardly continuous with it.

Structurally, Bon has its own canon, its own monasteries, its own Dzogchen transmission, and a full path with sutra, tantra, and Dzogchen divisions. To an outside observer, Bon monastic practice and Buddhist monastic practice are very similar, and the distinguishing features are lineage, terminology, and direction of circumambulation — Bonpos go counter-clockwise.

What actually differs #

For a practitioner, the differences amount to less than the four-school scheme suggests.

All four accept the same canon, ordain in the same Mulasarvastivada Vinaya, study Madhyamaka, practise tantra, take refuge and the bodhisattva vow, and do the same preliminary practices.

The real differences are: which highest practice is emphasised (Dzogchen, Mahamudra, Lamdre, or the Geluk combination of lamrim and Highest Yoga Tantra); how much study is required before tantric practice (Geluk most, Nyingma least); the balance of monastic and yogic life; whether leadership is hereditary, incarnational, or academic; and the interpretation of emptiness — Geluk’s rangtong position against the shentong views found in parts of Kagyu, Nyingma, and formerly Jonang.

The Rime movement #

In nineteenth-century Kham, eastern Tibet, a group of teachers — Jamyang Khyentse Wangpo, Jamgon Kongtrul, Chokgyur Lingpa, and others — began a deliberate effort to collect, preserve, and transmit teachings across sectarian lines.

Rime means “unbiased” or “non-sectarian.” The movement was partly a response to Geluk political dominance and to the real risk that minor lineages would be lost. Kongtrul’s Five Treasuries, an enormous compilation of teachings from every tradition, is its monument.

Rime is not a fifth school and does not propose that the differences do not matter. It proposes that a practitioner should hold one lineage as their own while studying and respecting others. Its influence on modern Tibetan Buddhism, particularly in the diaspora and in the West, has been very large — and the fourteenth Dalai Lama, a Geluk hierarch who teaches and receives transmissions across all four schools, is its most visible exponent.

Common questions #

Which school should I follow? Practically, the one whose teacher is available and whose presentation makes sense to you. Tibetan Buddhism is transmitted through a teacher, and lineage affiliation follows from that relationship rather than from comparing doctrinal profiles.

Is the Dalai Lama the head of Tibetan Buddhism? No. He is the most prominent figure and, historically, the political leader, and he is a Geluk hierarch — but not even the formal head of the Geluk school, which is the Ganden Tripa. Each school has its own head.

Are the differences important? Doctrinally, some are — the rangtong/shentong dispute is substantive. Institutionally, they matter for lineage and transmission. For most practitioners most of the time, less than the scheme implies.

Why does Nyingma have married lamas? Because it retained a strong non-monastic yogic tradition from the earlier diffusion, when tantric practice continued in family lineages through the period when monastic Buddhism collapsed.

Is Bon Buddhist? It is recognised as a distinct Tibetan religious tradition. It shares most of its structure, including Dzogchen, with Buddhism and maintains a separate lineage and canon. Whether it is best described as a form of Buddhism or as a parallel tradition is genuinely argued about.
