Srimad-Bhagavatam: Canto 6 - Chapter 1 - Verse 60
Sanskrit:
सुखाय दु:खमोक्षाय कुर्वाते दम्पती क्रिया: ।ततोऽनिवृत्तिरप्राप्तिर्दु:खस्य च सुखस्य च ॥ ६० ॥
ITRANS:
sukhāya duḥkha-mokṣāyakurvāte dampatī kriyāḥtato ’nivṛttir aprāptirduḥkhasya ca sukhasya ca
Translation:
As husband and wife, a man and woman plan together to attain happiness and decrease unhappiness, working jointly in many ways, but because their activities are full of desires, these activities are never a source of happiness, and they never diminish distress. On the contrary, they are a cause of great unhappiness.
