Hīnayāna · a historical term
In this framework, teachings on liberation from suffering through ethical conduct, meditation and wisdom form the foundation.
Three yānas · vehicles
A yāna is a vehicle: a way of travelling the Buddhist path. “Three vehicles” names different frameworks in different teachings.
Hīnayāna, Mahāyāna & Vajrayāna
Many Tibetan introductions use this threefold framework to explain foundations, motivation and methods. Thrangu Rinpoche’s presentation is one example.
Mahāyāna · Great Vehicle
Bodhicitta—the intention to attain Buddhahood for all beings—shapes the path. Compassion and the wisdom of emptiness develop through practices such as the six perfections.
Vajrayāna · Vajra Vehicle
Tantric methods work within the Mahāyāna aim of Buddhahood: mantra, Buddha forms and other lineage-specific practices. Empowerment and guidance belong to their setting.
These are overlapping accounts of a path. Vajrayāna retains Mahāyāna aims and foundational training; the labels do not describe three separate populations or a compulsory sequence for every Buddhist.
Why the word Hīnayāna needs context
Usually translated “Lesser Vehicle,” Hīnayāna originated as a disparaging label in Mahāyāna discourse. It also appears in Tibetan teaching frameworks and older books. Walpola Rahula rejects its use as a name for Theravāda.
Hīnayāna is not another name for Theravāda. Theravāda is a living tradition with its own histories, texts and accounts of the path. Its teachings include generosity, compassion and the bodhisatta ideal; “selfish Buddhism” would be a misleading description.
The three vehicles in many Mahāyāna sūtras
Here the distinction concerns three kinds of awakening and the paths associated with them.
- Śrāvakayāna · the hearer’s vehicle
The path of disciples who hear a Buddha’s teaching and realize liberation as arhats.
- Pratyekabuddhayāna · the independently awakened vehicle
The path of those who awaken without a Buddha’s teaching being available in their final life. This traditional ideal is not a modern school or simply a name for practising alone.
- Bodhisattvayāna · the bodhisattva vehicle
The path toward full Buddhahood for the benefit of beings, cultivating wisdom and the perfections.
The Lotus Sūtra presents these three as skilful means within the one Buddha vehicle, or ekayāna. Nyingma’s nine-vehicle system uses yet another arrangement.
