Vyādhi

Disease, bodily disorder that obstructs the practice of yoga. In Yogasūtra 1.30, vyādhi heads the list of the nine antarāya — mental obstacles — signaling that physical illness is not merely a medical problem but a spiritual barrier: the sick body scatters the mind and renders it incapable of [[samādhi]]. Haṭha Yoga, with its [[ṣaṭkarma]], āsanas, and [[prāṇāyāma]], presents itself as preventive and curative therapy: purifying the body is the condition for stilling the mind.
