Bhagavad Gita Chapter 12.13-12.14
adveṣṭā sarva-bhūtānāḿ
maitraḥ karuṇa eva ca
nirmamo nirahańkāraḥ
sama-duḥkha-sukhaḥ kṣamī
santuṣṭaḥ satataḿ yogī
yatātmā dṛḍha-niścayaḥ
mayy arpita-mano-buddhir
yo mad-bhaktaḥ sa me priyaḥ
Translation
One who is not envious but is a kind friend to all living entities, who does not think himself a proprietor and is free from false ego, who is equal in both happiness and distress, who is tolerant, always satisfied, self-controlled, and engaged in devotional service with determination, his mind and intelligence fixed on Me—such a devotee of Mine is very dear to Me.
