समः शत्रौ च मित्रे च तथा मानापमानयोः।
शीतोष्णसुखदुःखेषु समः सङ्गविवर्जितः।।12.18।।
12.18 He who is the same towards friend and foe, and so also in honour and dishonour; who is the same under cold, heat, happiness and sorrow, who is free from attachment to everything.
12.18 - 12.19 The absence of hate etc., towards foes, friends etc., has already been taught in the stanza beginning with, He who never hates any being (11.13). What is now taught is that eanimity to be practised even when such persons mentioned above are present before one who is superior to those having a general eanimous temperament referred to earlier. Who has no home, namely, who is not attached to home, etc., as he possesses firmness of mind with regard to the self. Because of this, he is same even in honour and dishonour. He who is devoted to Me and who is like this - he is dear to Me. Showing the superiority of Bhakti-Nistha over Atma-nistha, Sri Krsna now concludes in accordance with what is stated at the beginning of this chapter in Verse 2.
