Chapter 5 · The Yoga of Renunciation · Krishna said
Bhagavad Gita 5.19 — Equality is Brahman
इहैव तैर्जितः सर्गो येषां साम्ये स्थितं मनः। निर्दोषं हि समं ब्रह्म तस्माद् ब्रह्मणि ते स्थिताः ॥
ihaiva tairjitaḥ sargo yeṣāṃ sāmye sthitaṃ manaḥ | nirdoṣaṃ hi samaṃ brahma tasmād brahmaṇi te sthitāḥ ||
Meaning
Those whose minds rest in equality have conquered the world in this very life. Brahman is flawless and the same everywhere, so they abide in Brahman.
