Shankaracharya's commentary, trans. Alladi Mahadeva Sastry (1897)
[1]That which knows action and inaction, what ought to be done and what ought not to be done, fear and absence of fear, bondage and liberation, that intellect is Sattvic, O Partha.
BG 18.30
प्रवृत्तिं च निवृत्तिं च कार्याकार्ये भयाभये । बन्धं मोक्षं च या वेत्ति बुद्धिः सा पार्थ सात्त्विकी ॥
pravṛttiṃ ca nivṛttiṃ ca kāryākārye bhayābhaye | bandhaṃ mokṣaṃ ca yā vetti buddhiḥ sā pārtha sāttvikī ||
"Sāttvic buddhi: correctly knows pravṛtti-nivṛtti, kārya-akārya, fear-fearlessness, bondage-liberation."
