Bhagavad Gita 2.57

य: सर्वत्रानभिस्नेहस्तत्तत्प्राप्य शुभाशुभम् ।
नाभिनन्दति न द्वेष्टि तस्य प्रज्ञा प्रतिष्ठिता  ॥

ya: sarvatrānabhisnehas-tat-tat-prāpya śubhāśubham
nābhinandati na dveṣṭi tasya prajñā pratiṣṭhitā – 2.57

He who transcends his constricted fondness, and does not unduly compliment or condemn whatever auspicious or inauspicious meets him, his consciousness is stable and steady.
