(6) Ghora Âṅgirasa, after having communicated this (view of the sacrifice) to Krishna, the son of Devăkî --and he never thirsted again (after other knowledge)--said: 'Let a man, when his end approaches, take refuge with this Triad : "Thou art the imperishable," "Thou art the unchangeable," "Thou art the edge of Prâna."' On this subject there are two Rik verses (Rig-veda VIII, 6, 30):--

(10) The Person is all this, sacrifice, penance, Brahman, the highest immortal; he who knows this hidden in the cave (of the heart), he, O friend, scatters the knot of ignorance here on earth.

(10) Now therefore it would seem to follow, that both he who knows this (the true meaning of the syllable Om), and he who does not, perform the same sacrifice . But this is not so, for knowledge and ignorance are different. The sacrifice which a man performs with knowledge, faith, and the Upanishad is more powerful. This is the full account of the syllable Om.

(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.'

(1) What people call sacrifice (yagña), that is really abstinence (brahmakarya). For he who knows, obtains that (world of Brahman, which others obtain by sacrifice), by means of abstinence. What people call sacrifice (ishta), that is really abstinence, for by abstinence, having searched (ishtvâ), he obtains the Self.

(16) For him the Âdityas and the Visve Devas fulfil the third oblation. He who knows this, knows the full measure of the sacrifice, yea, he knows it.

(14) Yama said: 'I tell it thee, learn it from me, and when thou understandest that fire-sacrifice which leads to heaven, know, O Nakiketas, that it is the attainment of the endless worlds, and their firm support, hidden in darkness.'
