Bhagavad-gītā As It Is · Text 18.37
Knowledge, action, determination and happiness in the modes
यत्तदग्रे विषमिव परिणामेऽमृतोपमम् ।
तत्सुखं सात्त्विकं प्रोक्तमात्मबुद्धिप्रसादजम् ॥ ३७ ॥
yat tad agre viṣam iva
pariṇāme ’mṛtopamam
tat sukhaṁ sāttvikaṁ proktam
ātma-buddhi-prasāda-jam
That which in the beginning may be just like poison but at the end is just like nectar and which awakens one to self-realization is said to be happiness in the mode of goodness.
