1. 31

    यया धर्ममधर्मं च कार्यं चाकार्यमेव च । अयथावत्प्रजानाति बुद्धिः सा पार्थ राजसी ॥ १८-३१॥

    O Parth ( Arjun ) ! the Buddhi ( intellect ) is born of rajas with which one wrongly understands Dharma and Adharma ( virtue and vice ) as also what ought to be done and ought not to be done.

  2. 32

    अधर्मं धर्ममिति या मन्यते तमसावृता । सर्वार्थान्विपरीतांश्च बुद्धिः सा पार्थ तामसी ॥ १८-३२॥

    O Parth ( Arjun ) ! That Buddhi ( intellect ), which, enveloped in darkness, regards Adharma as Dharma ( vice as virtue ) and which reverses every value, is born of tamas.

  3. 33

    धृत्या यया धारयते मनःप्राणेन्द्रियक्रियाः । योगेनाव्यभिचारिण्या धृतिः सा पार्थ सात्त्विकी ॥ १८-३३॥

    O Parth ( Arjun ) ! That Dhrti (fortitude or persisting perseverance) by which one maintains the unswerving activities of the mind and vital force and these sense-organs through Yoga - that Dhrti is of the nature of Sattva.

  4. 34

    यया तु धर्मकामार्थान्धृत्या धारयतेऽर्जुन । प्रसङ्गेन फलाकाङ्क्षी धृतिः सा पार्थ राजसी ॥ १८-३४॥

    But, O Parth ( Arjun ), the firmness with which one holds on to righteousness, covetable things and wealth, being desirous of their fruits as the occasion for each arises, that firmness is born of rajas.

  5. 35

    यया स्वप्नं भयं शोकं विषादं मदमेव च । न विमुञ्चति दुर्मेधा धृतिः सा पार्थ तामसी ॥ १८-३५॥

    O Parth ( Arjun ) ! That Dhriti ( firmness ) is considered to be born of tamas due to which a person with a corrupt intellect does not give up sleep, fear, sorrow, despondency as also sensuality.
