This article explores the educational implications of using illness as a metaphor in Buddhist teachings, focusing on Kumārajīva’s translation of the Vimalakīrti Sutra, specifically the chapter “Mañjuśrī’s Inquiry About Illness”, with support from related Buddhist texts. The discussion is divided into two parts. The first examines the Buddhist perspective on illness, which distinguishes between physical and mental illness. Physical illness often stems from imbalances in the four elements and lifestyle habits, and both ancient Buddhist texts and modern health education stress the importance of prevention. Mental illness, on the other hand, arises from attachment to conditioned phenomena. Understanding emptiness and dependent origination allows one to see illness as a transient and transformative opportunity. The second part investigates the metaphorical meaning of illness through the discussion between Mañjuśrī and Vimalakīrti, highlighting the bodhisattva’s altruistic compassion in taking others’ suffering as his own. Interpreted through an educational lens, this suggests that teachers, by embodying the bodhisattva path and abandoning ego, can mindfully respond to each student’s unique challenges and approach education with non-dualistic compassion—thus realizing the ideal of nurturing every child.
