Tibetan Buddhism — Small

The Himalayan form of Buddhism: how it reached Tibet, its four schools, the Vajrayana path, the "Book of the Dead," and the saint Milarepa.

What it is

Tibetan Buddhism is the Mahayana Buddhism that developed in Tibet between roughly the 7th and 15th centuries, absorbing the late, tantric phase of Indian Buddhism and fusing it with older Tibetan religious life12. Its signature is the Vajrayana — the "Thunderbolt" or "Adamantine Path" — an esoteric system of mantra, mandala, deity visualization, and yoga, transmitted from guru to disciple under initiation1, alongside great monastic universities and the tulku system of reincarnating teachers, whose best-known holder is the Dalai Lama lineage2.

It arrived in Tibet's imperial age. King Song-tsen Gam-po (d. c. 650) is presented as the first Buddhist king; through royal marriages in 639 and 641, Buddhism entered Tibet, and his minister Sam-bhota devised the Tibetan alphabet on a Sanskrit model1. The decisive moment came under King Ti-song De-tsen in the later 8th century, who invited the tantric master Padma Sambhava from north-west India; he "established Buddhism firmly," founding the monastery of Sam-yé, in 1924 still the oldest of Tibet's large monasteries2. What reached Tibet was late Indian tantric Buddhism, "with their charms and mystic meanings"2 — which is why it looks so unlike the Buddhism of Sri Lanka or Thailand.

The four schools

The tradition organizes itself into four schools, with Bon — Tibet's pre-Buddhist religion, which has its own doctrine of rebirth — alongside them1. Nyingma ("Old School," the Red Hats) is the oldest, tracing itself to Padmasambhava, "the chief saint of the Red Hat sect"2; its summit teaching is dzogchen, the Great Perfection. Kagyu is the practice lineage, descending through Tilopa → Naropa → Marpa the Translator → Milarepa → Gampopa1. Sakya ("Tawny Earth") began as a reform movement and became the school of Tibet's first great political ascendancy: in 1270 Kublai Khan converted under a Sakya hierarch, binding Tibet to the Mongol empire21. Gelug (the Yellow Hats) is the 14th–15th-century reform of monastic discipline and dialectical study; the Dalai Lamas belong to it1.

The Vajrayana frame

Vajrayana is an accelerated method within Mahayana: after vows and initiation, the practitioner identifies with an enlightened deity in meditation (deity yoga) to realize the mind's own awakened nature. The Kagyu sources present two summit systems: Mahamudra ("the Great Symbol"), whose attainment is "the highest boon of The Great Symbol, ... Nirvana," and the Six Doctrines — practical yogas including tummo (inner heat), the illusory-body teaching, dream yoga, and phowa, the transference of consciousness1. These are advanced protocols demanding a qualified guru and years of preparation — historical techniques, not self-help exercises. The path is graded: purification, devotion to the teacher, initiation, then sustained meditation — a ladder Milarepa's biography lays out step by step1.

The Bardo

The West's most famous Tibetan text is the Bardo Thodol, the "Book of the Dead"3. Bardo is the intermediate state between death and rebirth — "whence one may be reborn in this world in a human body, or in the ghost-world... or in one of the paradise realms... or in one of the hells"3. Three stages: the Chikhai Bardo, where the Clear Light dawns at death; the Chonyid Bardo, where peaceful deities dawn (days one to seven) then wrathful ones (days eight to fourteen), all to be recognized as projections of one's own mind; the Sidpa Bardo, the drive toward rebirth3. The goal lies beyond all of it: "beyond all states of embodiment, beyond all hells, worlds, and heavens... it is called Nirvana"3. In the tradition it is a manual to be studied in life, not merely read over the dead.

Milarepa

No figure embodies the Tibetan ideal like Jetsun Milarepa. Cheated of his inheritance, the young man studies black magic and destroys thirty-five enemies and a harvest by sorcery — then is seized by remorse1. He finds Marpa the Translator, who subjects him to years of brutal probation — building and demolishing towers, withheld initiation — to burn out his negative karma, then initiates him1. Milarepa retreats to mountain caves, masters the yogas, attains realization in a single lifetime, and becomes Tibet's most beloved poet-saint1.

Where this comes from — an honest note

Nearly everything here is seen through one early window: the English translations of W. Y. Evans-Wentz (1927, 1928), rendered from Tibetan by the Sikkimese scholar Lama Kazi Dawa-Samdup, who wrote as "the mouthpiece of a Tibetan sage, of whom I was a recognized disciple"3. These are pioneering but early-20th-century renderings: Evans-Wentz frames Tibetan ideas with Theosophical-era parallels (likening the Kagyu to "moderate Anglicans among Christians")1, while Waddell (1895) and Bell (1924) were British colonial officials with that vantage point's limits42. Even "Lamaism" is a 19th-century European coinage, long retired by scholars. Treat this as the classic first doorway — the deeper layers mark where later scholarship revises it.

Pointers to the deeper layers

• DEEP: the two diffusions, the four schools' distinct doctrines and founders, the graduated path (lamrim), deity yoga as a practice system (with traditional prerequisites and warnings), the bardo sequence day by day, the Tilopa–Naropa–Marpa–Milarepa–Gampopa lineage tree.
• ULTRA-DEEP: the imperial-period history in full, the Sakya–Mongol and Gelug political ascendancies, the Bon substrate, Vajrayana completion-stage theory including the Six Doctrines, Dzogchen and Mahamudra, the canon-building translation projects, the scholarly debate over the Evans-Wentz renderings, an annotated source bibliography.
