चक्षुष्यो मधुरो ज्ञेयो रसधातुविवह्द्धनः / अम्लोत्तरो मनोहृद्यं तथा दीपनपाचनम्
cakṣuṣyo madhuro jñeyo rasadhātuvivahddhanaḥ / amlottaro manohṛdyaṃ tathā dīpanapācanam
รสหวานพึงรู้ว่าเป็นคุณแก่ดวงตา และยังรสธาตุรวมทั้งธาตุต่าง ๆ ให้เจริญ; ส่วนรสเปรี้ยวที่เด่นนั้นชื่นใจ และยังทำหน้าที่เป็นทีปนะ–ปาจนะ คือกระตุ้นไฟย่อยและช่วยการย่อย
Lord Vishnu (in discourse to Garuda/Vinata-putra)
Concept: Rasa impacts dhātu-puṣṭi and agni: madhura supports eyes and tissue nourishment; amla supports mental satisfaction and stimulates digestion (dīpana-pācana).
Vedantic Theme: Sattvic maintenance of the instrument (karaṇa-śarīra) for higher pursuits; harmony of mind (manas) and digestion (agni).
Application: Use appropriate sweet foods for depletion/dryness and eye strain (within kapha limits); use sour judiciously to kindle appetite/digestion when agni is low, avoiding excess in pitta conditions.
Primary Rasa: shanta
Secondary Rasa: adbhuta

It is described as cakṣuṣya (good for the eyes) and as nourishing—enhancing rasa and supporting dhātu growth.
It links sour predominance with dīpana (kindling appetite/agni) and pācana (supporting digestion/metabolism).
Balance tastes: use sweet foods for nourishment and steadiness, and use sour judiciously to stimulate appetite and digestion when appropriate.
