Verse
अनिष्टमिष्टं मिश्रं च त्रिविधं कर्मणः फलम् ।भवत्यत्यागिनां प्रेत्य न तु संन्यासिनां क्वचित् ॥
aniṣṭamiṣṭaṃ miśraṃ ca trividhaṃ karmaṇaḥ phalambhavatyatyāgināṃ pretya na tu saṃnyāsināṃ kvacit
The three kinds of result, pleasant, unpleasant and mixed, in this or other worlds, in this or another life are for the slaves of desire and ego; these things do not cling to the free spirit.
Gītā 18·12
