Bhagavad Gita Chapter 18, Verse 34

यया तु धर्मकामार्थान्धृत्या धारयतेऽर्जुन | प्रसङ्गेन फलाकाङ्क्षी धृतिः सा पार्थ राजसी ||

yayā tu dharma-kāmārthān dhṛtyā dhārayate 'rjuna prasaṅgena phalākāṅkṣī dhṛtiḥ sā pārtha rājasī

O Arjuna, that firmness by which one holds duty, desire, and wealth through attachment, desiring fruits, is rajasic.

Krishna explains rajasic firmness. 'Yayā tu dharma-kāmārthān dhṛtyā dhārayate'—that firmness (yayā dhṛtiḥ) by which one holds (dhārayate) duty, desire, and wealth (dharma-kāmārthān). 'Prasaṅgena phalākāṅkṣī dhṛtiḥ sā pārtha rājasī'—through attachment (prasaṅgena), desiring fruits (phalākāṅkṣī), that firmness (sā dhṛtiḥ) is rajasic (rājasī), O Arjuna (pārtha). This is rajasic firmness: holding onto duty, desire, and wealth through attachment, desiring fruits. This is the middle kind of firmness: driven by rajas (passion), which creates attachment to results. Unlike sattvic firmness (which is unwavering and detached), rajasic firmness is attached to outcomes and driven by desire. You maintain firmness, but it's motivated by attachment and desire for fruits. This is the path: firmness driven by passion rather than steady yoga.
