तदेव प्रीतये भूत्वा पुनर्दुःखाय जायते ।। तत्स्याद्दुःखात्मकं नास्ति न च किंचित्सुखात्मकम् ।। ३७।।

sanskrit

That at the outset is conducive to happiness but later brings in misery. Hence ultimately everything is of the nature of misery. There is nothing in fact of an invariably pleasurable nature.
