When to the knower all beings have become the very Self — what delusion, what sorrow, can there be for one who sees this oneness?
Isha Upanishad
ईशोपनिषद्
मूल श्लोकः
यस्मिन्सर्वाणि भूतान्यात्मैवाभूद्विजानतः। तत्र को मोहः कः शोक एकत्वमनुपश्यतः॥
yasmin sarvāṇi bhūtāny ātmaivābhūd vijānataḥ tatra ko mohaḥ kaḥ śoka ekatvam anupaśyataḥ
IsU 1.7
