Bhagavad Gita 13.28 · Krishna
The one who truly sees
समं सर्वेषु भूतेषु तिष्ठन्तं परमेश्वरम्।
विनश्यत्स्वविनश्यन्तं यः पश्यति स पश्यति॥
samaṃ sarveṣu bhūteṣu tiṣṭhantaṃ parameśvaramvinaśyatsvavinaśyantaṃ yaḥ paśyati sa paśyati
One who sees the supreme Lord dwelling equally in all beings, the undying within the dying, truly sees.
What it means
Krishna defines true seeing. Yah pashyati sa pashyati. The one who sees the supreme Lord dwelling equally in every being, the imperishable inside the perishable, that person truly sees. Everything else is only half-seeing.
The story
Arjuna sees perishing bodies about to fall. Krishna asks him to see the imperishable inside each one. That's the vision that changes everything, including how he fights.
In your life
Think of a hospice worker who sees each dying patient as whole and precious to the very end. That's true sight. Look at one person today, really look, and see what doesn't die.
True sight sees the undying in everyone.
