And since those deities, viz., the Viswedevas are in him, he is for that reason called Viswarupa. And since three goddesses adore and have recourse to that Lord of the universe, viz., Firmament, Water and Earth, he is for that reason called Tryamvaka. And since he always increaseth all kinds of wealth and wisheth the good of mankind in all their acts, he is for that reason called Siva. He possesseth a thousand eyes, or ten thousand eyes, and hath them on all sides. And since he protecteth this vast universe, he is for that reason called Mahadeva. And since he is great and ancient and is the source of life and of its continuance, and since his Phallic emblem is everlasting, he is for that reason called Sthanu. And since the solar and the lunar rays of light that appear in the world are spoken of as the hair on the Three-eyed one, he is for that reason called Vyomakesa. And since, afflicting Brahma and Indra and Varuna and Yama and Kuvera, he destroyeth them ultimately, he is for that reason called Hara. And since, he is the Past, the Future, and the Present, and, in fact, everything in the universe, and since he is the origin of the past, the future, and the present, he is for that reason called Bhava. The word Kapi is said to mean supreme, and Vrisha is said to mean righteousness. The illustrious God of gods, therefore, is called Vrishakapi.
