Bhagavad Gita · 6.30

यो मां पश्यति सर्वत्र सर्वं च मयि पश्यति।तस्याहं न प्रणश्यामि स च मे न प्रणश्यति॥

yo māṁ paśhyati sarvatra sarvaṁ cha mayi paśhyati tasyāhaṁ na praṇaśhyāmi sa cha me na praṇaśhyati

One who sees Me everywhere and sees everything in Me — I am never lost to such a person, nor is that person ever lost to Me.

— Bhagavad Gita 6.30
