Bhagavad Gīta Bhāshya and Tātparya
B.G 18.09 and 10
O Arjuna, when an action is performed as a duty without any attachment or expectation of results, such relinquishment is regarded as being in the mode of 'sāttva', i.e. goodness.
The wise relinquisher, filled with purity and free from doubts, neither hates unskilled actions nor is attached to skilled ones.

बहुचित्रजगद्बहुधाकरणात् परशक्तिरनन्तगुणः परमः ।
सुखरूपममुष्य पदं परमं स्मरतस्तु भविष्यति तत्सततम् ॥
"The one who has created this variegated vast universe with varied forms has infinite power and is of infinite auspicious qualities. He certainly bestows the highest state of bliss to those who meditate on his ever happy essence." -Dwādasha stōtra 4.3
