Bhagavad Gita 18.30

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

The intellect which knows the path of work and renunciation, what should be done and what should not be done, fear and fearlessness, bondage and liberation—that intellect is Sattvic (pure), O Arjuna.
