Markandeya said : Mudita, the favourite wife of the fire named Svaha, live in water. Svaha who was the lord of the sky, begot on his that wife a greatly sacred fire named Adbhuta. There is a tradition among the Brahmanas, namely that this fire is the ruler and the inner soul of all creatures.
मार्कण्डेय उवाच आपस्य मुदिता भार्या सहस्य परमा प्रिया। भूपतिर्भुवभर्ता च जनयत् पावकं परम्॥ भूतानां चापि सर्वेषां यं प्राहुः पावकं पतिम्। आत्मा भुवनभर्तेति सान्वयेषु द्विजातिषु॥
