Kuṣṭha-bheda-lakṣaṇa-nidāna and Śvitra (Kilāsa) Prognosis
कुष्ठोक्तं यच्च यच्चास्थिमज्जाशुक्रसमाश्रयम् / कृच्छ्रं मेदोमतञ्चैव याप्यं स्नाप्वास्थिमांसगम्
kuṣṭhoktaṃ yacca yaccāsthimajjāśukrasamāśrayam / kṛcchraṃ medomatañcaiva yāpyaṃ snāpvāsthimāṃsagam
凡被称为库ṣṭha(皮肤病)者,以及寄居于骨、骨髓与精液之中者——皆名为kṛcchra,属重症。与脂肪组织相系者亦复如是;而遍入筋腱、骨与肉者,则称为yāpya:虽为久病,仍可调治而得以控制。
Lord Vishnu (teaching Garuda/Vinata-putra)
Concept: Discrimination of disease by tissue-depth (dhatu-ashraya) and prognosis (krcchra vs yapya).
Vedantic Theme: Deha as anitya; knowledge (viveka) applied to embodied conditions without mistaking body for Self.
Application: Use depth of involvement (skin vs bone/marrow/semen) to judge severity and manage expectations; prioritize early intervention before deeper dhatus are affected.
Primary Rasa: shanta
Related Themes: Garuda Purana 1.164.32-35 (progression of kustha by dosha/dhatu involvement)
This verse classifies kuṣṭha by the deeper bodily tissues it occupies—bone, marrow, semen, fat, sinews, and flesh—implying that deeper tissue involvement makes the condition harder and more chronic.
Indirectly, it links embodied suffering to the condition of the physical body; in Garuda Purana’s broader teaching, bodily afflictions are part of lived consequences that shape one’s conduct and purification.
Treat chronic illness seriously and early: the verse emphasizes that deeper systemic involvement is harder to cure, encouraging timely care, disciplined living, and ethical conduct.
