Let us now invoke for our aid the Lord of Speech, the Designer of all things that are, the Inspirer of wisdom! May He, the ever-kindly, be well disposed to our summons, and may He, whose work is goodness, grant us His blessing!
Rig Veda 10.81.7

To the heavens be peace, to the sky and the earth; to the waters be peace, to plants and all trees; to the Gods be peace, to Brahman be peace, to all men be peace, again and again–peace also to me!
Shukla Yajur Veda 36.17

The Word, verily, is greater than name. The Word, in fact, makes known the Rig Veda, the Yajur Veda, the Sama Veda, the Atharva Veda as the fourth, and the ancient lore as the fifth: the Veda of Vedas, the ritual for ancestors, calculus, the augural sciences, ethics, political science, theology, knowledge of the spirits, military science, astrology, the science of snakes and of celestial beings. The Word also makes known heaven, earth, wind, space, the waters, fire, the Gods, men, animals, grass and trees. It also makes known what is right and wrong, truth and untruth, good and evil, what is pleasing and what is unpleasing. Verily, if there were no Word, there would be knowledge neither of right and wrong, nor of truth and untruth, nor of the pleasing and unpleasing. The Word makes all this known. Meditate on the Word.
Sama Veda, Chandogya Upanishad 7.2.1

By means of the hymns one attains this world, by the sacrificial formulas the space in-between, by holy chants the world revealed by the sages. With the syllable Aum as his sole support, the wise man attains that which is peaceful, unaging, deathless, fearless–the Supreme.
Atharva Veda, Prasna Upanishad 5.7

Homage to the source of health, and to the source of delight. Homage to the maker of health and to the maker of delight. Homage to the Auspicious and to the more Auspicious.
Yajur Veda Taittiriya Upanishad 4.5.8

Let him approach with humility a guru who is learned in the scriptures and established in Brahman. To such a seeker, whose mind is tranquil and senses controlled, and who has approached him in the proper manner, let the learned guru impart the science of Brahman, through which the true, Imperishable Being is realized.
Atharva Veda, Mundaka Upanishad 1.2.12?13

Having transcended the desire for sons, the desire for wealth, the desire for worlds, they go about as mendicants. For the desire for sons is the desire for wealth, and the desire for wealth is the desire for worlds. All these are nothing but desires. He, the atman, is not this, not this.
Shukla Yajur Veda, Brihadaranyaka Upanishad 4.4.22
