Bhaisajyaguru

In Mahāyāna soteriology Bhaisajyaguru attains buddhahood and presides over an eastern pure land named Vaiḍūryanirbhāsa (Pure Lapis Lazuli). Textual evidence (the Bhaiṣajya‑guru sūtra) and manuscript finds in Gandhāra and Bamiyan attest to his early popularity and transmission in the ancient northwest Indian world. As preserved in the sūtra tradition, he made twelve great vows committing him to curing suffering, aiding the sick and disabled, relieving poverty and hunger-driven crime, saving repentant prisoners, guiding beings back to the Dharma, and providing ‘‘inexhaustible things’’ required by beings; these vows form the ethical‑soteriological basis for his healing role.

Canonical iconography depicts Bhaisajyaguru in a Buddha form, typically wearing monastic robes and often holding a gallipot (medicine vessel). Some traditions portray him with blue or deep green skin — a color associated with lapis‑lazuli radiance — and East Asian temples commonly enshrine statues of him flanked by two attendant bodhisattvas, Sūryaprabha and Candraprabha (solar and lunar light). Tibetan gilt bronzes and East Asian images reproduce these features as devotional foci.

Bhaisajyaguru's primary function is therapeutic: he cures dukkha (suffering) through the "medicine of his teachings," the power of his twelve vows, and the merit generated by devotees' hearing his name, homage, recitation, and practice. The sūtra imagery emphasizes his luminous lapis‑lazuli radiance as part of his salvific presence. Devotional recitation of his name or mantra, ritual homage in Bhaisajyaguru halls, and faith in his vows are described as effective causes for receiving healing, material relief, liberation for repentant prisoners, and moral transformation; the archival teaching materials also present a standard devotional mantra used in closing healing prayers.
