भीष्मविक्रमदर्शनं तथा क्रौञ्चारुणव्यूहविधानम् | Bhīṣma’s Ascendancy and the Organization of the Krauñcāruṇa Formation
यया धर्ममधर्म च कार्य चाकार्यमेव च । अयथावत् प्रजानाति बुद्धि: सा पार्थ राजसी
yayā dharmam adharmaṁ ca kāryaṁ cākāryam eva ca | ayathāvat prajānāti buddhiḥ sā pārtha rājasī ||
हे पार्थ! जिस बुद्धि के द्वारा मनुष्य धर्म और अधर्म को तथा कर्तव्य और अकर्तव्य को यथार्थ नहीं जानता—वह बुद्धि राजसी है।
अजुन उवाच
A rajasic intellect is marked by confused moral discernment: it misjudges dharma vs. adharma and duty vs. forbidden action, leading to ethically unreliable decisions driven by passion, bias, or self-interest.
Within the Bhīṣma Parva’s battlefield instruction context, the discourse classifies types of intellect by the three guṇas; this verse defines the rajasic type as one that cannot correctly distinguish right from wrong and what should or should not be done.
