The Manifestation and Naming of Rudra / Nīlalohita
वायोः संचरणार्थानि भीमा सा प्रोच्यते तनुः / वैतान्यादीक्षितानां तु या स्थितिर्ब्रह्मवादिनाम्
vāyoḥ saṃcaraṇārthāni bhīmā sā procyate tanuḥ / vaitānyādīkṣitānāṃ tu yā sthitirbrahmavādinām
The form meant for the movement of Vāyu is proclaimed as Bhīmā. And such too is the station of the brahmavādins, initiated through vaitānya and other consecrations.
