Bhagavad Gita 5.19
Even in this world, those whose minds remain always balanced, fixed on the Supreme, conquer their earthly life; for the Supreme has neither blemish nor bias.
इहैव तैर्जितः सर्गो येषां साम्ये स्थितं मनः।
निर्दोषं हि समं ब्रह्म तस्माद्ब्रह्मणि ते स्थिताः॥ihaiva tairjitaḥ sargo yeṣāṃ sāmye sthitaṃ manaḥ|
nirdoṣaṃ hi samaṃ brahma tasmādbrahmaṇi te sthitāḥ||
