Bhagavad Gita Chapter 5, Verse 18

विद्याविनयसम्पन्ने ब्राह्मणे गवि हस्तिनि | शुनि चैव श्वपाके च पण्डिताः समदर्शिनः ||

vidyā-vinaya-sampanne brāhmaṇe gavi hastini śuni caiva śvapāke ca paṇḍitāḥ sama-darśinaḥ

The wise see the same Self in a Brahmin endowed with knowledge and humility, in a cow, in an elephant, in a dog, and even in an outcaste.

Krishna describes the yogi's equal vision (sama-darśinaḥ): the wise (paṇḍitāḥ) see the same Self in a Brahmin (brāhmaṇe) endowed with knowledge and humility (vidyā-vinaya-sampanne), in a cow (gavi), in an elephant (hastini), in a dog (śuni), and even in an outcaste (śvapāke). This is the state of true wisdom—seeing the same Self in all beings, regardless of their outer form or social status. The yogi doesn't see differences—they see the same Self everywhere. This equal vision is the foundation of karma yoga—when you see the Self in all, you can't be attached to particular outcomes or people because you recognize the same Self in everyone.
