Rudra-prasava-varṇana
The Manifestation and Naming of Rudra / Nīlalohita
विवेश तस्य तद्वायुमीशानस्तन मारुतः / तस्मान्नैनं परिवदेत्प्रवान्तं वायुमीश्वरम्
viveśa tasya tadvāyumīśānastana mārutaḥ / tasmānnainaṃ parivadetpravāntaṃ vāyumīśvaram
Then the Maruta, taking the form of Īśāna, entered that Vāyu; therefore let none revile the Lord of the wind as it blows.
