The Seers fashioned the Word by means of their mind, sifting it as with sieves the corn is sifted. Thus friends may recognize each other's friendship. An auspicious seal upon their word is set.

Rig Veda X, 71,2

They followed by sacrifice the path of the Word and found her entered in among the Seers. They led her forth and distributed her among many. In unison the seven Singers chant her.

Rig Veda X, 71,3

Yet certain ones, though seeing, may not see her, and other ones, though hearing, may not hear her. But to some the Word reveals herself quite freely, like fair-robed bride surrendering to her husband.

Rig Veda X, 71,4

Borne along and defiled by the stream of qualities, unsteady, wavering, bewildered, full of desire, distracted, one goes on into the state of self-conceit. In thinking This is I and That is mine one binds himself with himself, as does a bird with a snare.

Krishna Yajur Veda, Maitri Upanishad 3.2. uph, p. 418

When the body is in silent steadiness, breathe rhythmically through the nostrils with peaceful ebbing and flowing of breath. The chariot of the mind is drawn by wild horses, and those wild horses have to be tamed. Find a quiet retreat for the practice of yoga, sheltered from the wind, level and clean, free from rubbish, smoldering fires and ugliness, and where the sound of waters and the beauty of the place help thought and contemplation.

Krishna Yajur Veda, Svetasvatara Upanishad 2.9-10. Uupm, p. 88
