(13) To that pupil who has approached him respectfully, whose thoughts are not troubled by any desires, and who has obtained perfect peace, the wise teacher truly told that knowledge of Brahman through which he knows the eternal and true Person.

(13) 'A mortal who has heard this and embraced it, who has separated from it all qualities, and has thus reached the subtle Being, rejoices, because he has obtained what is a cause for rejoicing. The house (of Brahman) is open, I believe, O Nakiketas.'

(5) 'He who knows, let me think this, he is the Self, the mind is his divine eye . He, the Self, seeing these pleasures (which to others are hidden like a buried treasure of gold) through his divine eye, i. e. the mind, rejoices. 'The Devas who are in the world of Brahman meditate on that Self (as taught by Pragâpati to Indra, and by Indra to the Devas). Therefore all worlds belong to them, and all desires. He who knows that Self and understands it, obtains all worlds and all desires.' Thus said Pragâpati, yea, thus said Pragâpati.

(4) This very [doctrine] has been declared in the verse: — This eternal greatness of a Brahman Is not increased by deeds (karma), nor diminished. One should be familiar with it. By knowing it, One is not stained by evil action. Therefore, having this knowledge, having become calm, subdued, quiet, patiently enduring, and collected, one sees the Soul just in the soul. One sees everything as the Soul. Evil does not overcome him; he overcomes all evil. Evil does not burn him; he burns all evil. Free from evil, free from impurity, free from doubt, he becomes a Brahman. This is the Brahma-world, O king/ said Yajnavalkya. [Janaka said:] ' I will give you, noble Sir, the Videhas and myself also to be your slave.'

(6) Verily, he who knows attainment — for him, indeed, is attained what wish he wishes. The Ear, verily, is attainment, for in the ear all these Vedas are attained. The wish that he wishes is attained for him who knows this.

(3) 1. The knowledge of self. 2. The knowledge of God. 3. The knowledge of this world as it really is. 4. The knowledge of the next world as it really is. We shall now proceed to expound these four constituents in order.
