आहारशुद्धौ सत्त्वशुद्धिः, सत्त्वशुद्धौ ध्रुवा स्मृतिः, स्मृतिलम्भे सर्वग्रन्थीनां विप्रमोक्षः ।
āhāra-śuddhau sattva-śuddhiḥ, sattva-śuddhau dhruvā smṛtiḥ, smṛti-lambhe sarva-granthīnāṁ vipramokṣaḥ |
(Chāndogya Upaniṣad: 7.26.2)
“When there is purity of food, there is purity of mind. When there is purity of mind, there is steadfast remembrance. When there is retention of remembrance, there is definitive and complete release from all entanglements.”
