Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 25
Sanskrit:
अनित्यानात्मदु:खेषु विपर्ययमतिर्ह्यहम् ।द्वन्द्वारामस्तमोविष्टो न जाने त्वात्मन: प्रियम् ॥ २५ ॥
ITRANS:
anityānātma-duḥkheṣuviparyaya-matir hy ahamdvandvārāmas tamo-viṣṭona jāne tvātmanaḥ priyam
Translation:
Thus mistaking the temporary for the eternal, my body for my self, and sources of misery for sources of happiness, I have tried to take pleasure in material dualities. Covered in this way by ignorance, I could not recognize You as the real object of my love.
