Mahayana sutras promote the bodhisattva path because it aims to liberate all beings, reflecting a more inclusive vision of enlightenment than individual arhat attainment.
The arhat ideal, central to early Buddhist schools, focuses on individual liberation through one's own effort. An arhat achieves nirvana and escapes the cycle of rebirth. The bodhisattva path, by contrast, involves delaying one's own final liberation to help all sentient beings reach enlightenment. This represents a fundamental shift in what Mahayana sutras define as the highest spiritual achievement.
Mahayana texts like the Lotus Sutra and the Mahayana texts on bodhisattva practice present the bodhisattva path as spiritually superior because it expresses unlimited compassion. Rather than seeing enlightenment as a personal escape, Mahayana understands it as incomplete if others remain in suffering. This reflects the Mahayana principle that all beings possess Buddha-nature and deserve liberation.
Mahayana Buddhism emerged in the centuries after the Buddha's death, developing in regions like China, Tibet, and Japan where the religion encountered different cultural values. While earlier Buddhist schools remained closer to the original monastic emphasis on individual discipline, Mahayana responded to lay communities seeking meaningful spiritual paths available to everyone, not just monks.
The bodhisattva ideal addressed this need. It offered a vision where laypeople, rulers, and ordinary individuals could pursue enlightenment through compassion and service to others. The Bodhisattva Vows, found in texts like the Bodhisattva Precepts Sutra, became central to Mahayana practice, establishing a framework where any person could become a bodhisattva regardless of social status.
Mahayana sutras don't simply ignore the arhat ideal; they reinterpret it as a valid but incomplete spiritual achievement. The Lotus Sutra famously teaches that all paths ultimately lead to Buddhahood, including the arhat path. However, it presents arhats who cling only to their own liberation as having misunderstood the Buddha's full teaching.
This critique reflects Mahayana's expanded understanding of compassion. An arhat, having achieved personal nirvana, is seen as having stopped short of the deepest awakening. A Buddha, by contrast, actively works to liberate all beings—the mark of complete enlightenment. In this framework, pursuing Buddhahood through the bodhisattva path becomes the most complete response to suffering.
Mahayana sutras elevate specific bodhisattvas as objects of devotion and aspiration. Avalokiteshvara, the bodhisattva of compassion, and Manjushri, the bodhisattva of wisdom, appear throughout Mahayana texts as figures worthy of prayer and emulation. These bodhisattvas possess supernatural abilities and vast wisdom but consciously choose to remain in the world helping others.
This contrasts with the arhat, who, once enlightened, typically plays no further role in others' liberation. The Mahayana presentation makes bodhisattvas more accessible as role models—they are actively engaged in the world's suffering, demonstrating that spiritual development and helping others go hand in hand.
Mahayana developed new doctrinal concepts to support the bodhisattva path's emphasis. The doctrine of Buddha-nature teaches that all beings, including animals, possess the potential to become Buddhas. This universalism necessitates the bodhisattva path as the vehicle for awakening all beings.
Additionally, the concept of multiple Buddhas across time and space meant that Buddhahood remained attainable and relevant. Bodhisattvas could look to celestial Buddhas for guidance and inspiration. The Pure Land tradition exemplifies this: practitioners aspire to be reborn in Amitabha Buddha's Pure Land, where the bodhisattva path becomes easier to follow.
It's important to note that different Mahayana traditions emphasize this shift differently. Tibetan Buddhism, while Mahayana, maintains strong monasticism and monastic ideals. Pure Land Buddhism emphasizes devotion and rebirth in Buddha-lands. Zen Buddhism focuses on sudden insight but within a framework that values helping others.
Even within Mahayana, the arhat path isn't entirely rejected. Rather, it's understood as one valid expression within a larger system centered on the bodhisattva ideal. This flexibility allows Mahayana to encompass diverse practices while maintaining the bodhisattva path as the supreme aspiration.
