samaḥ śatrau ca mitre ca tathā mānāpamānayoḥ |
śītoṣṇa-sukha-duḥkheṣu samaḥ saṅga-vivarjitaḥ ||
tulya-nindā-stutir maunī santuṣṭo yena kenacit |
aniketaḥ sthira-matir bhaktimān me priyo naraḥ ||
(Śrīmad Bhagavad-gītā: 12.18–19)
“A person possessed of bhakti [who is] equal towards an enemy and a friend and honor and dishonor, equal towards cold and heat, happiness and suffering, free from attachment, equal towards defamation and praise, silent, satisfied with whatever comes, non-attached to house, and of steady mind is dear to me.”
