Roganidāna: Definitions, Fivefold Diagnostic Method, and Doṣa-wise Causes
हेत्वादिकार्त्स्न्यावयवैर्बलाबलविशेषषणम् / नक्तन्दिनार्धभुक्तांशैर्व्याधिकालो यथामलम्
hetvādikārtsnyāvayavairbalābalaviśeṣaṣaṇam / naktandinārdhabhuktāṃśairvyādhikālo yathāmalam
โดยพิจารณาเหตุและองค์ประกอบทั้งหมดของปัจจัยและส่วนต่าง ๆ ของกาย จงกำหนดลักษณะเฉพาะแห่งความแข็งแรงและความอ่อนกำลัง; และจากแบบแผนเช่นกินกลางคืน กินกลางวัน และกินเพียงครึ่งหนึ่ง จงเข้าใจลำดับเวลาของโรคให้สอดคล้องกับความกำเริบของมละ/โทษะ
Lord Vishnu (in instruction to Garuda/Vinatā-putra)
Dosha: Vata/Pitta/Kapha
Concept: Holistic assessment: hetu (causes) and aṅga/avayava (components) reveal bala–abala; dietary timing/quantity patterns indicate vyādhi-kāla aligned with mala-doṣa disturbance.
Vedantic Theme: Pramāṇa-based attentiveness (yathārtha-jñāna) to conditions and change; disciplined observation as a means to reduce duḥkha.
Application: Take a full history of causes and bodily factors; evaluate strength/weakness signs; note night-eating, day-eating, and half-meal habits to infer disease stage/progression and tailor regimen.
Primary Rasa: shanta
Related Themes: Garuda Purana 1.146.13 (aggravated malāḥ as universal nidāna); Garuda Purana 1.146.15 (specific ahita-vihāra/āhāra aggravators)
This verse stresses that accurate assessment of a person’s strength and weakness must be based on a complete review of causes and contributing factors, which guides proper understanding of illness and response.
It links disease timing to dietary patterns—such as eating at night or irregular restriction—and says prognosis should be inferred in line with the underlying ‘mala’ (morbid impurity/doṣa disturbance).
Maintain disciplined eating times and avoid habitual night-eating; when evaluating health issues, consider the full set of causes and lifestyle factors rather than a single symptom.
