Kuṣṭha-bheda-lakṣaṇa-nidāna and Śvitra (Kilāsa) Prognosis
भस्माच्छादितवत्कुर्याद्बाह्यं कुष्ठमुदाहृतम् / कुष्ठानि सप्तधा दोषैः पृथग्द्वन्द्वैः समागतैः
bhasmācchāditavatkuryādbāhyaṃ kuṣṭhamudāhṛtam / kuṣṭhāni saptadhā doṣaiḥ pṛthagdvandvaiḥ samāgataiḥ
வெளிப்புறத் தோலை சாம்பல் பூசப்பட்டதுபோல் ஆக்கும் நோய் ‘பாஹ்ய குஷ்டம்’ எனப்படுகிறது. தோஷங்கள் தனித்தனியாகவோ அல்லது இரட்டைக் கூட்டாகவோ சேர்ந்தால் குஷ்டம் ஏழு வகையாகும்.
Lord Vishnu (in dialogue with Garuda/Vinata-putra)
Dosha: Vata/Pitta/Kapha
Concept: Disease classification arises from doṣa imbalance (single or dual doṣa combinations).
Vedantic Theme: Deha as prakṛti-vikāra; the embodied condition is mutable and governed by guṇas/doṣas, encouraging vairāgya and disciplined living.
Application: Observe symptoms and consider doṣa causation; seek appropriate regimen rather than fatalism.
Primary Rasa: bibhatsa
Secondary Rasa: karuna

It is a condition where the outer skin looks ash-covered, and the text explicitly labels this appearance as bāhya (external) kuṣṭha.
It states a sevenfold classification, caused by the doṣas either individually or through paired combinations, reflecting a tridoṣa-based diagnostic model.
Use the teaching as a reminder to correct imbalances early (diet, habits, cleanliness) and to keep spiritual focus, since bodily conditions are changeable and time-bound.
