दुःखं च भोगकालेऽपि तेषामन्ते महत्तरम् ।सुखं विषयसम्पृक्तं विषसम्पृक्तभक्तवत् ॥ ६५१ ॥
In plain words
Suffering accompanies worldly enjoyment even while it is happening, and becomes far greater at the end. Sensual pleasure is tainted by objects, just like food mixed with poison.
Close to the Sanskrit
And pain is present even at the time of enjoyment, and at their end it is greater; happiness is associated with objects, like food mixed with poison.
