देवस्तुतिवर्णनं नाम सप्तमोऽध्यायः
Description of the prayer by the Devas – Chapter 7
Lord Vishnu said (teaching the Devas how to get Lord Shiva in their control)
प्रणवं पूर्वमुच्चार्य नमः पश्चादुदाहरेत् |
शिवायेति ततः पश्चाच्छुभद्वय मतः परम् || 25 ||
First the Pranava (Om) should be pronounced, then Namah should be said. After that, Shivaya. (These) two (words, Namah and Shivaya) are considered the most auspicious.
