Bhagwad Gita
Chapter 13, Verse 35
क्षेत्रक्षेत्रज्ञयोरेवमन्तरं ज्ञानचक्षुषा।भूतप्रकृतिमोक्षं च ये विदुर्यान्ति ते परम्।।13.35।।
One who knowingly sees this difference between the body and the owner of the body and can understand the process of liberation from this bondage, also attains to the supreme goal.
