Bhagavad Gita 18.30

प्रवृत्तिं च निवृत्तिं च कार्याकार्ये भयाभये।बन्धं मोक्षं च या वेत्ति बुद्धिः सा पार्थ सात्त्विकी

pravṛittiṁ cha nivṛittiṁ cha kāryākārye bhayābhaye bandhaṁ mokṣhaṁ cha yā vetti buddhiḥ sā pārtha sāttvikī

That which knoweth energy and abstinence, what ought to be done and what ought not to be done, fear and fearlessness, bondage and liberation, that Reason is pure, O Pârtha.
