Cikitsā-sāra: Doṣa Nidāna–Lakṣaṇa, Agni, Ajīrṇa/Āma Cikitsā, Daśamūla, and Prognostic Signs
रसवीर्यविपाकानामाश्रयं द्रव्यमुत्तमम् / रसपाकान्तरस्थायि सर्वद्रव्याश्रयं द्रुतम्
rasavīryavipākānāmāśrayaṃ dravyamuttamam / rasapākāntarasthāyi sarvadravyāśrayaṃ drutam
درویہ ہی اعلیٰ ترین سہارا ہے جس میں رس، وِیریہ اور وِپاک قائم رہتے ہیں۔ رس اور ہضم کے بدلتے مرحلوں میں بھی جو برقرار رہے، وہی تمام درویات کا بنیاد و آسرہ ہے۔
Lord Vishnu (in instruction to Garuda/Vinata-putra)
Concept: Dravya as the substratum in which rasa, virya, and vipaka inhere; continuity of substance through transformations.
Vedantic Theme: Substratum-and-attributes (adhara–adheya) reasoning; persistence of an underlying basis amid change (parinama-vada style analysis).
Application: In diagnosis and pharmacology, distinguish the stable substance from its changing sensory/digestive manifestations; avoid judging a drug only by immediate taste.
Primary Rasa: shanta
Related Themes: Garuda Purana 1.168.23 (virya/vipaka definitions); Garuda Purana 1.168.24-25 (chikitsa-anga and clinical assessment)
Because, as this verse states, taste, potency, and post-digestive effect are understood to inhere in a substance; without dravya they have no locus.
It indicates that even when taste or digestive outcomes change, the underlying substance remains the continuing support through those stages.
When choosing herbs or foods, consider the whole substance (not only immediate taste), since its potency and post-digestive effect shape the long-term result.
