Bhagavad-gītā As It Is · Text 18.38
Knowledge, action, determination and happiness in the modes
विषयेन्द्रियसंयोगाद्यत्तदग्रेऽमृतोपमम् ।
परिणामे विषमिव तत्सुखं राजसं स्मृतम् ॥ ३८ ॥
viṣayendriya-saṁyogād
yat tad agre ’mṛtopamam
pariṇāme viṣam iva
tat sukhaṁ rājasaṁ smṛtam
That happiness which is derived from contact of the senses with their objects and which appears like nectar at first but poison at the end is said to be of the nature of passion.
