एतच्छ्रुत्वा सम्परिगृह्य मर्त्यः प्रवृह्य धर्म्यमणुमेतमाप्य । स मोदते मोदनीयँ हि लब्ध्वा विवृतँ सद्म नचिकेतसं मन्ये ॥

ॐ

English Translation

The mortal who has heard this and comprehended it well, who has separated that Atman, the very soul of dharma, from all physical objects and has realised the subtle essence, rejoices because he has obtained that which is the cause of rejoicing. The Abode of Brahman, I believe, is open for Nachiketa. 

ॐ

Commentary

Again having heard this, the true âtman which I shall explain to you—from the presence of the preceptor and well-grasped it as his own Self, having abstracted the virtuous âtman from the body, etc., and having realized this subtle âtman, the learned mortal rejoices having obtained what gives him joy, i.e., the âtman. The door of such abode of Brahman is, I think, wide open for you, Nachikêtas. The drift is ‘I think you worthy of emancipation.’
