Upagupta

Upagupta is the fourth patriarch in the Chan list and one of the more substantively attested early figures, the subject of an extensive corpus of Sanskrit narrative literature centered in Mathurā^[1]. The *Aśokāvadāna* presents him as the spiritual preceptor of the emperor Aśoka (r. c. 268–232 BCE), and John Strong's monograph *The Legend and Cult of Upagupta* documents a continuous regional cult that survives in modern Burma and Thailand, where he is invoked as *U Pakuṭ* and propitiated as a protector against monsoon storms^[2].

Two narrative motifs dominate the Upagupta legend. The first is his subjugation of Māra: when Māra disrupted his preaching, Upagupta countered by binding three corpses—a dog, a snake, and a man—around Māra's neck as a perfumed garland that Māra could not remove until he humbled himself; afterwards Māra is said to have taken refuge in the Dharma^[3]. The second is his role as imperial preceptor: he led Aśoka on a pilgrimage to the great sites of the Buddha's life, identifying each location and confirming the emperor's commitment to Buddhist patronage^[4].

The Sarvāstivāda school of northwest India regarded Upagupta as their fifth patriarch, parallel to but distinct from the Chan reckoning. Dumoulin notes that the early Chan lineage drew on these northwestern materials but reorganized them around Mahāyāna concerns, producing the twenty-eight-name sequence that became canonical from the *Jǐngdé Chuándēng Lù* onward^[5]. Upagupta is described in Chan sources as "the buddha without marks" (*alakṣaṇaka-buddha*)—accomplished in realization without possessing the thirty-two physical *lakṣaṇas* of a *cakravartin*^[6].
