Classical Vedanta · part of the Mahabharata
Bhagavad Gita 6.29
Seeing the same Self everywhere, in all beings
सर्वभूतस्थमात्मानं सर्वभूतानि चात्मनि। ईक्षते योगयुक्तात्मा सर्वत्र समदर्शनः॥
With the mind harmonized by yoga, one sees the Self abiding in all beings and all beings in the Self; everywhere one sees the same.
What this verse points to
Sameness of vision, samadarshana, is offered here as a result rather than a discipline. It is what the harmonised mind sees, not a way of looking you should force on yourself before you can see it.
That matters practically. Trying to feel equally toward everyone by effort tends to produce strain and quiet dishonesty. The verse locates the change further upstream, in the steadiness of the mind that does the seeing.
Sit with it
Do not try to generate equal feeling. Sit until the mind settles, then notice how your view of a difficult person has shifted on its own.
About the Bhagavad Gita
The Bhagavad Gita is a 700-verse dialogue set on the battlefield of Kurukshetra, in which Krishna counsels the warrior Arjuna at the moment he refuses to fight. Across eighteen chapters it draws together the paths of action, devotion, and knowledge into a single teaching on how to act without being bound by action. It sits inside the Bhishma Parva of the Mahabharata and has been the most widely commented-upon text in the Vedantic tradition, from Shankara onward.
