Arjuna asked Sri Krishna Who is your dearest Bhakta ? Lord Krishna answered,--
adwestaa sarva-bhutanaam maitrah karuna eva cha I
nirmamo nitahamkarah sama-dukho-sukhah kshami II ...13
santushtah satatam yogi yatatma drrrnishayah II
mayy-arpita-mano-buddhir-yor-mad-bhaktah sa me priyah II....14
He who hates no creature, and is friendly and compassionate towards all, who is free from the feelings of " I and mine", even-minded in pain and pleasure, forbearing, ever content, steady in meditation, self-controlled, and possessed of firm conviction, with mind and intellect fixed on Me--- he who is thus devoted to Me, is dear to Me.
