He finds happiness in his own Self and enjoys eternal bliss, whose heart does not yearn for the contacts of the earth and whose Self is one with the Everlasting.
Translated by Shri Purohit Swami
With the self unattached to external contacts, he finds happiness in the Self; with the self engaged in the meditation of Brahman, he attains endless happiness.
Translated by Swami Sivananda
