Mahayana Buddhism: A Comprehensive Overview

刘瑞闫

Mahayana Buddhism originated in ancient India and took shape roughly between the 1st century BCE and the 1st century CE, evolving incrementally on the foundations of Early Buddhism and Nikaya Buddhism. Derived from a Sanskrit term meaning "great vehicle", the word Mahayana symbolizes the Dharma’s capacity to ferry innumerable sentient beings across worldly afflictions to ultimate liberation. Modern Buddhist academia avoids the pejorative ancient label "Hinayana" for the concurrent early Buddhist lineage, referring to it instead as Theravada Buddhism.

Its doctrinal emergence was closely tied to socio-economic shifts across ancient India. Booming urban commerce fostered a growing lay devotee community whose spiritual demands diverged from early Buddhism’s primary emphasis on monastic seclusion and individual emancipation. Practitioners dedicated to altruistic compassion elaborated latent doctrines from ancient Buddhist scriptures and compiled an extensive corpus of new Mahayana sutras, establishing a distinct doctrinal framework largely rooted in the ideological evolution of the Mahasanghika school of early Buddhism.

The core tenet of Mahayana Buddhism centres on the Bodhisattva ideal. Practitioners first generate Bodhicitta, the supreme aspiration to attain full Buddhahood for oneself and deliver all suffering sentient beings. This vow constitutes the fundamental divide separating Mahayana from other Buddhist traditions. Unlike vehicles focused on personal enlightenment and Arhatship to escape cyclic existence, Mahayana affirms the inherent potential for Buddhahood dwelling within every living being. Its ultimate spiritual goal is full Buddhahood, upon which enlightened Buddhas voluntarily return to the mortal world to rescue beings trapped in birth, aging, illness and death.

For practical cultivation, Mahayana outlines two core disciplines: the Six Paramitas and the Four Ways of Embracing Sentient Beings.
The Six Paramitas consist of generosity, morality, forbearance, diligence, meditation and prajna (transcendental wisdom). Progressing sequentially, generosity eliminates greed; precepts regulate conduct against unwholesome deeds; patience overcomes resentment; diligence prevents spiritual slackness; meditation calms scattered thoughts; and prajna embodies primordial insight into the true nature of all phenomena. Interdependently, these virtues cultivate self-perfection alongside compassionate service to others.
The Four Embracings serve as the Bodhisattva’s interpersonal guidance for guiding beings: generosity, kind speech, beneficial action and sympathetic companionship. Through material aid, gentle persuasion, practical assistance and participating in ordinary lives, Bodhisattvas draw people toward the Dharma. This system dismantled the exclusive monastic monopoly on full spiritual practice, enabling lay followers to walk the Bodhisattva path amid family duties and daily labour, accumulating merit within secular life.

Ontologically, Mahayana is grounded in the doctrine of dependent origination and emptiness (sunyata). All physical phenomena and mental experiences arise from converging conditional causes and cease when such conditions dissolve, possessing no fixed, independent inherent existence. This dual emptiness refers to non-self of individuals and non-self of all dharmas, dispelling clinging to an enduring ego or permanently substantial things. Emptiness does not equate to nihilistic nothingness; rather, genuine emptiness manifests as phenomenal existence, encapsulating the Middle Way of true emptiness and wonderful manifestation.
Two major Indian philosophical schools developed from this ontology: the Madhyamaka founded by Nagarjuna, anchored on Prajna sutras to elaborate the Middle Way transcending extremes of eternalism and annihilationism; and the Yogacara (Vijnanavada or Consciousness-Only School) established by Asanga and Vasubandhu, which posits all phenomenal existence manifests from seeds stored within the eighth alaya-vijnana, explaining cosmic formation and dependent origination from the perspective of consciousness.

After doctrinal maturation, Mahayana travelled via the Silk Road into China around the turn of the Common Era. Over successive dynasties, Chinese monastics translated canonical texts, syncretised Buddhist teachings with indigenous Confucian and Daoist thought and established uniquely Chinese Mahayana sects:

The Tiantai School bases its teachings on the Lotus Sutra, advancing the doctrine of the Threefold Truth interpenetration: emptiness, conventional existence and the Middle Truth are inseparably unified.
​
The Huayan School centres on the Avatamsaka Sutra, expounding dependent arising of all dharmas from the Dharma-dhatu and unobstructed interpenetration of all phenomena.
​
The Faxiang (Dharmalaksana) School was introduced to China by Xuanzang from India, systematically inheriting Yogacara Consciousness-Only theories and elaborating on the eight layers of consciousness and cosmic transformation.
​
Chan (Zen) rejects excessive scriptural commentary, adhering to "no establishment of written words, direct pointing at the original mind" to attain instant enlightenment, ranking among China’s most popular folk Buddhist schools.
​
Pure Land simplifies cultivation prerequisites, resting on Amitabha Buddha’s original vows; practitioners attain rebirth in the Western Pure Land through sincere faith and oral Buddha-recitation, the most widespread devotional practice among common believers.
​
The Vinaya School specialises in the study and observance of monastic precepts, regulating monastic daily routines and disciplinary codes.

From China’s Han heartland, Mahayana subsequently spread to the Korean Peninsula, Japan and Vietnam, evolving region-specific traditions fused with native customs and indigenous philosophies. Across centuries, its core ethos of compassionate altruism and worldly benefaction has profoundly shaped East Asian folklore, literature, architecture, fine arts and ethical systems, leaving indelible imprints on traditional charity, seasonal customs and philosophical evolution. To this day, Mahayana remains East Asia’s numerically dominant and doctrinally most comprehensive Buddhist tradition.
