The Yoga of Liberation by Renunciation

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.
