The god Krishna says;
“I love the man who hates not nor exults, who mourns not nor desires … who is the same to friend and foe, whether he be respected or despised, the same in heat and cold, in pleasure and in pain, who has put away attachment and remains unmoved by praise or blame… contented with whatever comes his way”
