एतच्छ्रुत्वा सम्परिगृह्य मर्त्यः
प्रवृह्य धर्म्यमणुमेतमाप्य ।
स मोदते मोदनीयँ हि लब्ध्वा
विवृतँ सद्म नचिकेतसं मन्ये ॥ १३॥
etacchrutvā samparigṛhya martyaḥ
pravṛhya dharmyamaṇumetamāpya .
sa modate modanīyam̐ hi labdhvā
vivṛtam̐ sadma naciketasaṃ manye .. 13..
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.
Swami Vivekananda Says —
He who knows this secret gives up all his vain desires, and attains this superfine perception, and thus becomes ever blessed. Nachiketas, that is the way to blessedness.[Source]
