Bhagavad Gita 2.57
He who, wherever he goes, is not attached to any person or place by ties of flesh; who accepts good and evil alike, neither welcoming the one nor shrinking from the other—take him to be one who is merged in the Infinite.
यः सर्वत्रानभिस्नेहस्तत्तत्प्राप्य शुभाशुभम्।
नाभिनन्दति न द्वेष्टि तस्य प्रज्ञा प्रतिष्ठिता॥yaḥ sarvatrānabhisnehastattatprāpya śubhāśubham|
nābhinandati na dveṣṭi tasya prajñā pratiṣṭhitā||
