The Yoga of Liberation by Renunciation

Krishna explains the relationship between action, fruits, and attachment. 'Aniṣṭam iṣṭaṁ miśraṁ ca trividhaṁ karmaṇaḥ phalam'—the fruits of action (karmaṇaḥ phalam) are of three kinds (trividham): unfavorable (aniṣṭam), favorable (iṣṭam), and mixed (miśram). 'Bhavaty atyāgināṁ pretya'—these fruits occur (bhavati) for those attached to fruits (atyāginām) after death (pretya), meaning they experience the consequences. 'Na tu sannyāsināṁ kvacit'—but not (na tu) for renunciates (sannyāsinām) at any time (kvacit). This is the key teaching: if you're attached to fruits, you experience three kinds of results—good, bad, mixed. But if you're a true renunciate (relinquishing fruits), you don't experience these consequences. This sets up the teaching about the three kinds of action according to gunas: sattvic, rajasic, tamasic.
