Bhagavad Gita - Chapter 12 - Verse 13-14
mayy-arpita-mano-buddhir yo mad-bhaktah sa me priyah One who is devoid of hatred, who is friendly and compassionate to all living beings, who is devoid of any sense of possessiveness, free of egotism, objective in all circumstances, forgiving, a self-satisfied practitioner of yoga, selfcontrolled, of strong determination, and whose mind and intelligence is engaged in thinking of Me – that person is My devotee and is thus very dear to Me.
