2. This syllable Om is indeed Brahman. this syllable is the highest. whosoever knows this syllable obtains all that he desires. – Katha Upanishad

4. The knowing self is not born; it does not die. it has not sprung from anything; nothing has sprung from it. birthless, eternal, everlasting and ancient, it is not killed when the body is killed. – Katha Upanishad
5. The wise man beholds all beings in the self and the self in all
   beings; for that reason, he does not hate anyone. – Isha Upanishad
