यत्तदग्रे विषमिव परिणामेऽमृतोपमम् ।
तत्सुखं सात्त्विकं प्रोक्तमात्मबुद्धिप्रसादजम् ॥

yat-tad-agre viṣam-iva pariṇāme’mṛtopamam
tat-sukhaṃ sāttvikaṃ proktam-ātma-buddhi-prasādajam – 37

That happiness (sukha) is considered sāttvika, wherein one rejoices through spiritual practice and begets end of misery, which is like poison to start with, but like nectar in the end, which is born from the placidity of Self-knowledge.
