The holy rites of fire pertaining to Śiva - Verse 97

Śailādi said: The devotee shall repeat the Mūla mantra once and bow down to the lord of Devas. Then he shall perform three Prāṇāyāmas of the Sagarbha type (i.e., with the repetition of Oṃ) as approved of by all yogins. After sprinkling water he shall pour ghee on to the sacrificial twig. O great sage, then he shall consign it into the kindled fire.
