Bhagavad Gita Chapter 12.18-12.19
samaḥ śatrau ca mitre ca
santuṣṭo yena kenacit
bhaktimān me priyo naraḥ
One who is equal to friends and enemies, who is equipoised in honor and dishonor, heat and cold, happiness and distress, fame and infamy, who is always free from contaminating association, always silent and satisfied with anything, who doesn’t care for any residence, who is fixed in knowledge and who is engaged in devotional service—such a person is very dear to Me.
