The Katha Upanishad Eknath Easwaran version

Hidden in the heart of every creature
Exists the Self, subtler than the subtlest,
Greater than the greatest. They go beyond
All sorrow who extinguish their self-will
And behold the glory of the Self
Through the grace of the Lord of Love.

Though one sits in meditation in a
Particular place, the Self within
Can exercise his influence far away.
Though still, he moves everything everywhere.

When the wise realize the Self,
Formless in the midst of forms, changeless
In the midst of change, omnipresent
And supreme, they go beyond sorrow.

The Self cannot be known through study
Of the scriptures, nor through the intellect,
Nor through hearing discourses about it.
The Self can be attained only by those
Whom the Self chooses. Verily unto them
Does the Self reveal himself.
