All pervading Shiva

"Yudhishthira said, 'O son of the River Ganga, thou hast heard all the names of Maheshwara, the Lord of
the universe. Do thou tell us, O grandsire, all the names that are applied, O puissant one, unto Him who
is called Isa and Sambhu. Do thou tell us all those names that are applied unto Him who is called Vabhru
or vast, Him that has the universe for his form, Him that is the illustrious preceptor of all the deities and
the Asuras, that is called Swayambhu (self-creating) and that is the cause of the origin and dissolution of
the universe. Do thou tell us also of the puissance of Mahadeva.'

"Bhishma said, 'I am quite incompetent to recite the virtues of Mahadeva of highest intelligence. He
pervades all things in the universe and yet is not seen anywhere. He is the creator of universal self and
the Pragna (knowing) self and he is their master. All the deities, from Brahman to the Pisachas, adore and worship him.

He transcends both Prakriti and Purusha. It is of Him that Rishis,
conversant with Yoga and possessing a knowledge of the tattwas, think and reflect. He is indestructible
and Supreme Brahman. He is both existent and non-existent. Agitating both Prakriti and Purusha by
means of His energy, He created therefrom the universal lord of creatures, viz., Brahma. Who is there
that is competent to tell the virtues of that god of gods, that is endued with supreme Intelligence? Man is
subject to conception (in the mother's womb), birth, decrepitude, and death. Being such, what man like
me is competent to understand Bhava? Only Narayana, O son, that bearer of the discus and the mace,
can comprehend Mahadeva. He is without deterioration. He is the foremost of all beings in attributes. He
is Vishnu, because of his pervading the universe.
