Bhagavad Gita · 12.19

तुल्यनिन्दास्तुतिर्मौनी सन्तुष्टो येनकेनचित्।अनिकेतः स्थिरमतिर्भक्तिमान्मे प्रियो नरः॥

tulya-nindā-stutir maunī santuṣhṭo yena kenachit aniketaḥ sthira-matir bhaktimān me priyo naraḥ

One who regards blame and praise equally, who is silent and reflective, content with anything, without a fixed home, steady-minded, and full of devotion — such a person is dear to me.

— Bhagavad Gita 12.19
