प्र ते ब्रवीमि तदु मे निबोध स्वर्ग्यमग्निं नचिकेतः प्रजानन् । अनन्तलोकाप्तिमथो प्रतिष्ठां विद्धि त्वमेतं निहितं गुहायाम् ॥ १४॥

ॐ

English Translation

Yama said: I know well the Fire-sacrifice, which leads to Heaven and I will explain it to you. Listen to me. Know this Fire to be the means of attaining Heaven. It is the support of the universe; it is hidden in the hearts of the wise. 

ॐ

Commentary

This is Death’s declaration. I will tell thee what has been solicited by thee; attend to what I say with concentrated mind. I know the fire, Oh Nachikêtas, which helps one to heaven; ‘I will tell thee and attend’ are expressions used to concentrate the disciple’s intellect; now he praises the fire, know this fire as leading to heaven and as the stay of the universe in its form of virât and as located in the intelligence of knowing men.
