Ut is heaven, gî the sky, tha the earth. Ut is the sun, gî the air, tha the fire. Ut is the Sâma-veda, gî the Yagur-veda, tha the Rig-veda. Speech yields the milk, which is the milk of speech itself, to him who thus knowing meditates on those syllables of the name of udgîtha, he becomes rich in food and able to eat food.

In plain words: The three parts of the word also stand for heaven, sky, and earth; for the sun, air, and fire; and for the three Vedas. Whoever meditates this way receives the gifts of speech and will have plenty of food and good health to enjoy it.
