Srimad-Bhagavatam: Canto 6 - Chapter 1 - Verse 59


स्मृत्वेहायां परिक्लेशं तत: फलविपर्ययम् ।अभयं चाप्यनीहायां सङ्कल्पाद्विरमेत्कवि: ॥ ५९ ॥


smṛtvehāyāṁ parikleśaṁtataḥ phala-viparyayamabhayaṁ cāpy anīhāyāṁsaṅkalpād viramet kaviḥ


Remembering the great trouble found in the field of activities performed for fruitive results, and remembering how one receives the reverse of the results one desires — whether from material actions or from the fruitive activities recommended in the Vedic literatures — an intelligent man should cease from the desire for fruitive actions, for by such endeavors one cannot achieve the ultimate goal of life. On the other hand, if one acts without desires for fruitive results — in other words, if one engages in devotional activities — he can achieve the highest goal of life with freedom from miserable conditions. Considering this, one should cease from material desires.
