Arhat

Lore & Background

In early Buddhist schools, a range of views existed on the attainment of arhats. Schools derived from the Mahāsāṃghika, the Kāśyapīya, and the Sarvāstivāda accepted the fallibility and imperfection of arhats. The Dharmaguptaka sect believed that the Buddha and those of the Two Vehicles have one and the same liberation but followed different noble paths. The Mahīśāsaka and the Theravāda regarded arhats and buddhas as having attained the same liberation, differing only in the path taken and qualities developed. In Theravāda Buddhism, an arahant has eliminated all unwholesome roots and fetters, and upon death will not be reborn. The Buddha himself is identified as an arhat. After attaining nirvana, the five aggregates continue to function until physical death, when parinirvana occurs. In Mahāyāna Buddhism, arhats are considered inferior to fully enlightened buddhas, and followers are urged to take up the bodhisattva path instead of falling back to the level of arhats.

The concept of the arhat is central to Buddhist soteriology, representing the ideal of personal liberation from suffering and rebirth. However, its significance and legacy are marked by deep doctrinal divisions. Early schools debated whether arhats were perfect and infallible or still subject to ignorance and relapse. The Mahāsāṃghika and Sarvāstivāda traditions held arhats to be fallible, while Theravāda and Mahīśāsaka saw them as equal to buddhas in liberation. Mahāyāna Buddhism reoriented the spiritual ideal toward the bodhisattva, viewing arhatship as a lesser, even selfish, goal. The arhat thus embodies both the achievement of nirvana and the evolving tensions within Buddhist thought about the nature of enlightenment and the path to it.

The Essence of Arhatship

The term arhat, drawn from the Sanskrit verbal root meaning 'to deserve,' originally carried the simple sense of being worthy or meriting honor—a usage already present in the Ṛgveda. In the broader religious landscape of pre-Buddhist India, the word denoted a saintly figure closely tied to ascetic practice and miraculous power. Buddhism, however, drew a deliberate line of separation. For the Buddha and his followers, the arhat was no longer defined by supernatural feats or extreme austerities. Instead, the defining achievement became an interior transformation: direct insight into the true nature of existence, the realization of nirvana, and the complete severing of the chain of rebirth. This redefinition shifted the center of spiritual authority from external displays of power to an irreversible inner liberation. The arhat, in this framework, is one who has seen through the architecture of suffering and stepped beyond it, no longer accumulating the karmic 'assets' that would propel another cycle of birth. The word thus encapsulates not merely a title but a terminal state of spiritual development, a person who has, in the most literal sense, earned the right to be free.

Doctrinal Divisions Over Arhat Perfection

Among the early Buddhist schools, no single consensus emerged on whether an arhat was truly flawless. Several lineages descended from the Mahāsāṃghika—namely the Ekavyāvahārika, Lokottaravāda, Bahuśrutīya, Prajñaptivāda, and Caitika—insisted that arhats remained fallible and still subject to residual ignorance, while elevating the buddha and bodhisattva as transcendent figures beyond comparison. The Kāśyapīya school echoed this skepticism, teaching that an arhat had not fully eradicated desire and could even relapse into lower states. The Sarvāstivāda tradition held a parallel position, a stance vividly illustrated in the Nāgadatta Sūtra, where the demon Māra, disguised as a bhikṣuṇī's father, urges her to settle for the 'easier' goal of arhatship rather than the far more demanding path to full buddhahood. At the other end of the spectrum, the Mahīśāsaka and Theravāda traditions affirmed that arhats and buddhas share the same ultimate liberation, differing only in the specific path walked and the breadth of qualities cultivated along the way. The Dharmaguptaka sect occupied a middle ground, acknowledging identical liberation but distinct noble paths.

The Theravāda Path to Final Release

Within Theravāda Buddhism, the arhat occupies a precise and well-defined position. The individual has uprooted every unwholesome root that sustains the fetters binding a being to samsara, and upon death will not be reborn in any realm. The Pali Canon itself sometimes uses the title tathāgata as a synonym for arhat, though that term more commonly designates the Buddha alone. The Buddha, in fact, is first identified as an arhat before being called a buddha, underscoring that arhatship is the foundational achievement. After attaining nirvana while still alive, the five aggregates—physical form, sensation, perception, mental formations, and consciousness—continue to operate, sustained by bodily vitality. This living state is called the nirvana element with residue remaining. Only when the arhat passes away and the body disintegrates do the aggregates cease entirely, marking parinirvana: total release from the misery of cyclic existence. The fifth-century commentator Buddhaghosa regarded arhats as having fully completed the path, and the Pali Canon records Ānanda describing four distinct routes by which a monastic may reach this terminal liberation.

Mahāyāna Recontextualization and the Arhat in Art

The rise of Mahāyāna Buddhism introduced a significant reordering of spiritual priorities. Rather than celebrating arhatship as the highest personal goal, Mahāyāna teachings urged practitioners to embrace the bodhisattva path and explicitly warned against retreating to the level of arhats and śrāvakas. This created a theological tension that persisted across centuries. Yet even within Theravāda circles, senior arhats gradually came to be understood as extending their personal liberation into a broader, bodhisattva-like enterprise, working for others in their own distinctive manner. In Mahāyāna tradition, a celebrated group of Eighteen Arhats—each with a distinct name and personality—was said to be awaiting the future Buddha Maitreya. Other numerical groupings of six, eight, sixteen, one hundred, and five hundred also appear in texts and artistic depictions. In East Asia, these figures are known as luohan or lohan, and they occupy a cultural niche comparable to that of Christian saints, apostles, or the early disciples who shaped the faith after its founder's departure.
