Cikitsā-sāra: Doṣa Nidāna–Lakṣaṇa, Agni, Ajīrṇa/Āma Cikitsā, Daśamūla, and Prognostic Signs
शीतोष्णं लवणं वीर्यमथ वा शक्तिरिष्यते / रसानां द्विविधः पाको कटुरेव च
śītoṣṇaṃ lavaṇaṃ vīryamatha vā śaktiriṣyate / rasānāṃ dvividhaḥ pāko kaṭureva ca
وِیریہ کو ٹھنڈا اور گرم—دو قسم کا مانا گیا ہے؛ یہی مؤثر طاقت (شکتی) ہے۔ رسوں کا وِپاک دو طرح کا ہے؛ یہاں کَٹُو (تیز) صورتِ نتیجہ بیان ہوا ہے۔
Lord Vishnu (in instruction to Garuda/Vinata-putra)
Concept: Virya is twofold (cooling/heating) as operative shakti; vipaka is classified as twofold, with katu as a resultant category stated here.
Vedantic Theme: Knowledge by lakshana (definition) and bheda (classification); power (shakti) inferred from effects.
Application: When selecting diet/drugs, assess heating vs cooling potency and expected post-digestive outcome; do not rely on initial taste alone for predicting systemic effect.
Primary Rasa: shanta
Related Themes: Garuda Purana 1.168.22 (dravya as substratum); Garuda Purana 1.168.25 (assessment before treatment)
This verse defines virya primarily as twofold—cooling (śīta) and heating (uṣṇa)—and equates it with the functional power (śakti) of a substance.
It states that the post-digestive transformation of tastes is twofold, and points to pungency (kaṭu) as a noted resulting type in this formulation.
When assessing a food or herb, track not only its taste but whether it acts heating or cooling and what it tends to become after digestion, since that influences long-term balance.
