The Saiva Upanishads - 5
Rudra Upanishad (2)
Uma Herself is the form of Vishnu. Vishnu Himself is the form of the moon. Therefore, those who worship Lord Vishnu, worship Siva Himself. And those who worship Siva, worship Lord Vishnu in reality. Those who envy and hate Sri Rudra, are actually hating Sri Vishnu. Those who decry Lord Siva, decry Vishnu Himself.
Rudra is the generator of the seed. Vishnu is the embryo of the seed. Siva Himself is Brahma and Brahma Himself is Agni. Rudra is full of Brahma and Vishnu. The whole world is full of Agni and Soma. The masculine gender is Lord Siva. The feminine gender is Sri Bhavani Devi. All the mobile and immobile creation of this universe, is filled up with Uma and Rudra. The Vyakta is Sri Uma, and the Avyakta is Lord Siva. The combination of Uma and Sankara is Vishnu.
Hence everybody should prostrate to Sri Maha Vishnu with great devotion. He is the Atman. He is the Paramatman. He is the Antaratman. Brahma is the Antaratman. Siva is the Paramatman. Vishnu is the Eternal Atman of all this universe. This whole creation of Svarga, Martya and Patala Lokas is a big tree. Vishnu is the top portion (branches) of this tree. Brahma is the stem. The root is Lord Siva.
The effect is Vishnu. The action is Brahma. The cause is Siva. For the benefit of the worlds. Rudra has taken these three forms.
