Bhagavad Gita Chapter 2, Verse 57

यः सर्वत्रानभिस्नेहस्तत्तत्प्राप्य शुभाशुभम् । नाभिनन्दति न द्वेष्टि तस्य प्रज्ञा प्रतिष्ठिता ॥

yaḥ sarvatrānabhisnehas tat tat prāpya śubhāśubham | nābhinandati na dveṣṭi tasya prajñā pratiṣṭhitā ||

One who is without attachment everywhere, who neither rejoices excessively on obtaining good nor hates on encountering bad—their wisdom is established.

After describing how the wise remain unshaken in suffering, Krishna now reveals what happens when good or bad comes. 'Sarvatrānabhisnehaḥ'—without sneha (attachment) everywhere. Not cold or uncaring, just not caught in desperate clinging. When life brings 'śubhāśubham'—pleasant and unpleasant things, such a person neither 'abhinandati' (rejoices excessively) nor 'dveṣṭi' (hates). Why? 'Anabhisnehaḥ'—no attachment means outcomes don't trigger extreme reactions. You appreciate good without making it your identity; you face bad without hatred. Then 'prajñā pratiṣṭhitā'—wisdom is steady, established.
