Someone says "Buddhism" and you think you know what that is. But Buddhism in Thailand is visibly different from Buddhism in Tibet, which is different from Zen, which is different from Pure Land.
Are they different religions? Different approaches to the same thing? Competing schools?
The answer: Different strategies for the same realization, shaped by culture and individual constitution.
It's like different routes up the same mountain. They look completely different—desert path vs. forest path vs. rock scramble—but they all lead to the peak.
Where it's strong: Southeast Asia (Thailand, Sri Lanka, Burma)
Core approach:
Real practice:
Strength: Crystal-clear teaching, proven results, fast for committed practitioners
Limitation: Can appear to devalue helping others (focus on personal liberation)
Where it's strong: East Asia (Tibet, China, Japan, Korea, Vietnam)
Core approach:
Real practice:
Strength: Accessible to everyone, doesn't require monastic life, integrates compassion and philosophy
Limitation: Can seem to dilute the direct practice with extra layers
Where it's strong: Tibet (primarily)
Core approach:
Real practice:
Strength: Fastest transformation for those ready, addresses all dimensions of consciousness
Limitation: Can be misused, requires skilled teacher, looks "unbuddhist" to outsiders
They all teach:
They differ on:
Choose Theravada if:
Choose Mahayana if:
Choose Vajrayana if:
Yes. Many people:
The schools developed in different cultures for different people. You're not betraying one by borrowing from another.
Sarah (Theravada): Sits daily meditation, follows ethical precepts strictly, eventually becomes a nun, achieves Arhatship through her own practice. Her path is clear, direct, solitary.
Michael (Mahayana): Meditates, studies Buddhist philosophy, does compassion practices, takes refuge in Buddha/Dharma/Sangha, stays a layperson, works toward Bodhisattva realization while raising a family. His path is devotional, philosophical, relational.
Tenzin (Vajrayana): Works with a Tibetan teacher, practices guru yoga, visualizes as deity, does mantra work and ritual, undergoes initiation, develops rapid transformation. His path is esoteric, guru-dependent, using all dimensions of consciousness.
All three are genuine Buddhist practitioners. All three may achieve realization. Their paths look completely different.
Buddhism is not "one thing with variations." It's a family of practices all pointing at the same realization—emptiness, non-self, liberation from suffering—through different routes.
This is why you can study all three and find deep compatibility. They're not competing; they're complementary approaches for different people at different life stages.
Your job: Find which school resonates with your temperament and stage. Follow it deeply. The path you take with genuine commitment matters more than which path you take.
This page maps Buddhism's schools along the doctrinal-soteriological axis — Mahayana / Theravada / Vajrayana, the bodhisattva ideal vs the arhant ideal vs tantric methods. Faxian's chronicle adds a second axis the doctrinal frame typically misses: disciplinary-textual lineages.
By Faxian's time (405 CE), the post-Buddha Sangha had split into eighteen schools — but the eighteen are not the same as the modern tripartite. They are Vinaya-recension lineages descended from the Second Council split at Vaisali (c. 380-340 BCE; see Second Council Vaisali — Weapons Laid Down Tope (Faxian)). Mahasanghika, Sthavira, Sarvastivadah, Mahisasakah, Theravada, and a dozen others, each maintaining its own Vinaya recension, its own Abhidharma compendium, its own line of teacher-student transmission. Faxian's chronicle describes the disciplinary differences as "small and trivial, as when one opens and another shuts" (Ch. XXXVI line 1556).
What this adds: a monk's school-affiliation in 405 CE was multi-axial. A given monk could be Mahasanghika-Mahayana, or Sarvastivadah-Hinayana, or Mahisasakah-Mahayana. The Vinaya recension was one identity-axis; the soteriological position was another. See Vinaya Textual Archaeology Faxian Mahasanghika Discovery.
Also at the Faxian moment: Mahayana and Hinayana operationally coexisted within the same monasteries. The Pataliputra Mahayana monastery and a Hinayana monastery sat side by side with a combined 600-700 monks sharing the common store and the Mahasanghika Vinaya — see Mahayana-Hinayana Coexistence Faxian Survey 405 CE. The school-distinction was real but operationally light. The hardening into separate institutions came in the centuries after Faxian, and the modern tripartite framing this page maps is the late-stage flattening of an originally multi-axial taxonomy.
The implication for school-choice: the modern frame asks you to pick a tradition. The 5th-century Sangha did not require the choice. A practitioner could study Mahayana texts and live in a Vinaya-Hinayana monastery and follow the disciplinary code of a third school across his career. If your temperament resists the modern single-tradition-pick framing, you are not behaving anomalously — you are reverting to the pre-divergence pattern that operated for the first nine hundred years of Buddhist history.
