Bhagavad Gita 14.25

Who looks equally upon honor and dishonor, loves friends and foes alike, and abandons all initiative, such is he who transcends the qualities.

मानापमानयोस्तुल्यस्तुल्यो मित्रारिपक्षयोः।सर्वारम्भपरित्यागी गुणातीतः स उच्यते॥

mānāpamānayostulyastulyo mitrāripakṣayoḥ|sarvārambhaparityāgī guṇātītaḥ sa ucyate||
